Labcorp Genetics (formerly Invitae), Labcorp RCV001878581 SCV002122294 uncertain significance Autosomal dominant nonsyndromic hearing loss 1; Progressive microcephaly-seizures-cortical blindness-developmental delay syndrome 2024-01-19 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 308 of the DIAPH1 protein (p.Ile308Val). This variant is present in population databases (rs752555506, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DIAPH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1358258). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
GeneDx RCV003442924 SCV004170209 uncertain significance not provided 2023-04-06 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
