GeneDx RCV000427658 SCV000518267 uncertain significance not provided 2021-06-07 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; This variant is associated with the following publications: (PMID: 27535533)
Labcorp Genetics (formerly Invitae), Labcorp RCV000792934 SCV000932263 uncertain significance Developmental and epileptic encephalopathy, 1; Autosomal dominant nonsyndromic hearing loss 65; Caused by mutation in the TBC1 domain family, member 24 2024-11-19 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 341 of the TBC1D24 protein (p.Arg341His). This variant is present in population databases (rs754727069, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TBC1D24-related conditions. ClinVar contains an entry for this variant (Variation ID: 380328). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TBC1D24 protein function with a negative predictive value of 95%. 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 RCV003278798 SCV003961172 likely benign Inborn genetic diseases 2023-03-20 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
