This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 29 of the DTNA protein (p.Arg29Cys). This variant is present in population databases (rs781374642, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with DTNA-related conditions. ClinVar contains an entry for this variant (Variation ID: 2234416). 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 DTNA protein function. 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.

Record last updated Nov 10, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
