Illumina Laboratory Services, Illumina RCV000402053 SCV000449400 uncertain significance Cranioectodermal dysplasia 4 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Invitae RCV001366163 SCV001562458 uncertain significance Asphyxiating thoracic dystrophy 5; Senior-Loken syndrome 8 2022-01-04 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 740 of the WDR19 protein (p.Tyr740His). This variant is not present in population databases (gnomAD no frequency). 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: 348741). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.
