Genes affected
DCHS1 (HGNC:13681): (dachsous cadherin-related 1) This gene is a member of the cadherin superfamily whose members encode calcium-dependent cell-cell adhesion molecules. The encoded protein has a signal peptide, 27 cadherin repeat domains and a unique cytoplasmic region. This particular cadherin family member is expressed in fibroblasts but not in melanocytes or keratinocytes. The cell-cell adhesion of fibroblasts is thought to be necessary for wound healing.

DCHS1-AS1 (HGNC:40650): (DCHS1 antisense RNA 1)

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 02, 2023This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 3275 of the DCHS1 protein (p.Gln3275Arg). This variant is present in population databases (rs770014749, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with DCHS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1518872). 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 DCHS1 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. -
