Level 1A clinical annotations must also be supported by at least one publication in addition to a clinical guideline or drug label with variant-specific prescribing guidance.
Invitae RCV000046895 SCV000074908 pathogenic Cystic fibrosis 2024-01-24 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 1152 of the CFTR protein (p.Asp1152His). This variant is present in population databases (rs75541969, gnomAD 0.3%). This missense change has been observed in individuals with congenital absence of the vas deferens and classic cystic fibrosis (PMID: 7739684, 11883825, 15858154, 15987793, 16429425, 17003641, 17594398, 18301294, 19843100, 20460946, 21520337, 22156145, 23082198, 23951356, 25304080). ClinVar contains an entry for this variant (Variation ID: 35867). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt CFTR protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects CFTR function (PMID: 9804160, 23891399, 25033378). For these reasons, this variant has been classified as Pathogenic.

GeneDx RCV000325638 SCV000329250 pathogenic not provided 2018-07-12 criteria provided, single submitter clinical testing The D1152H pathogenic variant has been reported previously is association with cystic fibrosis and congenital bilateral absence of the vas deferens (Chillon et al., 1995; Burgel et al., 2010; Terlizzi et al., 2015). A retrospective case review revealed that the patients homozygous and compound heterozygous for the D1152H variant exhibited very mild clinical expression (Terlizzi et al., 2015). The D1152H variant is observed in 29/10,142 (0.3%) alleles from individuals of Ashkenazi Jewish background in large population cohorts, and no individuals were reported to be homozygous (Lek et al., 2016). The D1152H variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In vitro functional studies indicated that the D1152H variant results in a protein whose chloride transport is approximately 57% that of wild-type (VanGoor et al., 2014; LaRusch et al., 2014). We interpret D1152H as a pathogenic variant.

Quest Diagnostics Nichols Institute San Juan Capistrano RCV000325638 SCV000601100 likely pathogenic not provided 2023-08-03 criteria provided, single submitter clinical testing The CFTR c.3454G>C (p.Asp1152His) variant has been reported in the published literature in individuals with cystic fibrosis and may be associated with a milder presentation than typical pathogenic variants in CFTR (PMIDs: 27659740 (2017), 27214204 (2016), 27086061 (2016), 26755536 (2016), 25910067 (2015), 25583415 (2015)). This variant is also reported in individuals with CFTR-related disorders (PMIDs: 7739684 (1995), 22020151 (2012), 23951356 (2013), 27171515 (2016), 27738188 (2017)). In addition, published functional studies demonstrate that this variant partially reduces chloride transport activity, affects proper chloride channel gating, alters bicarbonate conductance, and results in decreased conductance and permeability (PMIDs: 32414100 (2020), 25033378 (2014), 23891399 (2014), 9804160 (1998)). The frequency of this variant in the general population, 0.0026 (27/10360 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Based on the available information, this variant is classified as likely pathogenic.
ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000325638 SCV000603066 pathogenic not provided 2023-10-24 criteria provided, single submitter clinical testing The CFTR c.3454G>C; p.Asp1152His variant (rs75541969) is reported in the literature in multiple individuals affected with classic cystic fibrosis or CFTR-related disorders (Chillon 1995, Gallati 2009, Highsmith 2005, LaRusch 2014, Masson 2013, Steiner 2011, Sosnay 2013, CFTR2 database). This variant is also reported in ClinVar (Variation ID: 35867), and is found in the general population with an overall allele frequency of 0.038% (106/282326 alleles) in the Genome Aggregation Database. The aspartic acid at codon 1152 is moderately conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.657). Functional characterization of the variant protein indicates a significant reduction in chloride and bicarbonate transport activity (LaRusch 2014, Sosnay 2013, Van Goor 2014, Vankeerberghen 1998). Genotype-phenotype correlation studies have demonstrated that this variant, in combination with another pathogenic CFTR variant (e.g. p.Phe508del), is associated with highly variable clinical presentations, ranging from asymptomatic to pancreatic insufficient CF (Burgel 2010, Mussaffi 2006, Terlizzi 2015, CFTR2 database). Based on available information, the p.Asp1152His variant is classified as pathogenic with varying clinical consequences. References: Link to CFTR2 database: http://cftr2.org/ Burgel P et al.

Illumina Laboratory Services, Illumina RCV000046895 SCV000916188 pathogenic Cystic fibrosis 2018-08-22 criteria provided, single submitter clinical testing The CFTR c.3454G>C (p.Asp1152His) missense variant has been described in 12 studies in patients with CFTR-related disorders, including in at least 22 in a homozygous state and 179 in a compound heterozygous state (Chillon et al. 1995; Dayangac et al. 2004; Highsmith et al. 2005; Mussaffi et al. 2006; Augarten et al. 2008; Burgel et al. 2010; Peleg et al. 2011; Steiner et al. 2011; Tomaiuolo et al. 2011; Sosnay et al. 2013; LaRusch et al. 2014; Terlizzi et al. 2015). The p.Asp1152His variant, when in combination with another variant known to cause CFTR-related disorders, is associated with an extremely variable phenotype ranging from asymptomatic to cystic fibrosis. The variant is often associated with mild clinical expression, mild pulmonary disease and pancreatic sufficiency (Augarten et al. 2008; Burgel et al. 2010; La Rush et al. 2014). The p.Asp1152His variant was found in a heterozygous state in one of 2957 controls and is reported at a frequency of 0.002859 in the Ashkenazi Jewish population of the Genome Aggregation Database. Functional studies on the p.Asp1152His variant showed chloride transport activity is 57.4% of the wild type (Van Goor et al. 2014). La Rusch et al. (2014) report that the p.Asp1152His variant causes a narrowing of the channel diameter which would affect conductance properties. The p.Asp1152His variant was shown to exhibit normal chloride function in HEK293 cells with significantly reduced bicarbonate permeability and conductance (LaRusch et al. 2014). Vankeerberghen et al. (1998) demonstrated in Xenopus oocytes that the p.Asp1152His variant did not alter the permeability sequence of the CFTR channels but led to whole cell cAMP activated chloride currents that were significantly reduced compared to wild type indicating that the variant interfere with the proper gating of the chloride channels. Based on the collective evidence, the p.Asp1152His variant is classified as pathogenic for CFTR-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.

Ambry Genetics RCV000046895 SCV001181807 pathogenic Cystic fibrosis 2022-01-13 criteria provided, single submitter clinical testing The p.D1152H pathogenic mutation (also known as c.3454G>C), located in coding exon 21 of the CFTR gene, results from a G to C substitution at nucleotide position 3454. The aspartic acid at codon 1152 is replaced by histidine, an amino acid with similar properties. In one study, 45 individuals with a p.D1152H allele in trans with another CFTR mutation were identified with features including bronchiectasis and congenital bilateral absence of the vas deferens (CBAVD) (Burgel PR et al. Clin. Genet., 2010 Apr;77:355-64). Numerous studies have concluded this mutation is often associated with a mild cystic fibrosis presentation or CFTR-related disorder characterized by mild pulmonary disease, varying clinical expression, and prolonged survival (Schulz A et al. J. Cyst. Fibros., 2016 Sep;15:641-4; Gaitch N et al. Pancreatology Apr;16:515-22; Lucarelli M et al. Mol. Med., 2015 Apr;21:257-75) and it has been described as a variant of varying clinical consequences (VVCC) (Sosnay PR et al. Pediatr. Clin. North Am., 2016 08;63:585-98; Salinas DB et al. PLoS ONE, 2016 May;11:e0155624). Functional in vitro studies found that cells carrying this pathogenic mutation retained the ability to conduct chloride (Sosnay PR et al. Nat. Genet. 2013 Oct; 45(10):1160-7). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.

PreventionGenetics, part of Exact Sciences RCV001826514 SCV004111459 likely pathogenic CFTR-related disorder 2024-01-30 criteria provided, single submitter clinical testing The CFTR c.3454G>C variant is predicted to result in the amino acid substitution p.Asp1152His. This variant has been found in 358 patients who also carried a p.Phe508del variant (cftr2.org). These individuals had slightly elevated chloride concentration of 43 mEq/L on a sweat test (normal <40 mEq/L). Individuals less than 20 years of age had normal lung function, but 27% had pancreatic insufficiency (cftr2.org; Sosnay et al. 2013. PubMed ID: 23974870). This variant, when present with a second pathogenic variant, has been reported in patients with variable clinical presentations including bronchiectasis, pancreas insufficiency, chronic cough, and congenital bilateral absence of the vas deferens (Feldmann et al. 2003. PubMed ID: 12955726; Terlizzi et al. 2015. PubMed ID: 25583415). This variant is reported in 0.26% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. This variant is interpreted as likely pathogenic.
