Labcorp Genetics (formerly Invitae), Labcorp RCV001312509 SCV001502965 uncertain significance Autosomal dominant nonsyndromic hearing loss 1; Progressive microcephaly-seizures-cortical blindness-developmental delay syndrome 2022-02-04 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1013853). This variant has not been reported in the literature in individuals affected with DIAPH1-related conditions. This variant is present in population databases (rs368435886, gnomAD 0.003%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 453 of the DIAPH1 protein (p.Lys453Arg).
