Invitae RCV001306032 SCV001495388 uncertain significance Asphyxiating thoracic dystrophy 5; Senior-Loken syndrome 8 2024-01-31 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1174 of the WDR19 protein (p.Arg1174His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with WDR19-related conditions. ClinVar contains an entry for this variant (Variation ID: 1008660). 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 not expected to disrupt WDR19 protein function with a negative predictive value of 80%. 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.
Ambry Genetics RCV002543150 SCV003544846 uncertain significance Inborn genetic diseases 2022-05-04 criteria provided, single submitter clinical testing The c.3521G>A (p.R1174H) alteration is located in exon 32 (coding exon 32) of the WDR19 gene. This alteration results from a G to A substitution at nucleotide position 3521, causing the arginine (R) at amino acid position 1174 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
