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.

The c.9883G>C (p.E3295Q) alteration is located in exon 21 (coding exon 20) of the DCHS1 gene. This alteration results from a G to C substitution at nucleotide position 9883, causing the glutamic acid (E) at amino acid position 3295 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. 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. This variant has not been reported in the literature in individuals affected with DCHS1-related conditions. This variant is present in population databases (rs773543020, gnomAD 0.008%). This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 3295 of the DCHS1 protein (p.Glu3295Gln). -
