Invitae RCV000793746 SCV000933115 uncertain significance Hoyeraal-Hreidarsson syndrome; Autosomal recessive dyskeratosis congenita 2022-10-05 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 640672). This variant has not been reported in the literature in individuals affected with DCLRE1B-related conditions. This variant is present in population databases (rs202133913, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 418 of the DCLRE1B protein (p.Ser418Phe).
Ambry Genetics RCV003279066 SCV003958941 uncertain significance Inborn genetic diseases 2023-03-21 criteria provided, single submitter clinical testing The c.1253C>T (p.S418F) alteration is located in exon 4 (coding exon 4) of the DCLRE1B gene. This alteration results from a C to T substitution at nucleotide position 1253, causing the serine (S) at amino acid position 418 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
