Genes affected

DSG2 (HGNC:3049): (desmoglein 2) This gene encodes a member of the desmoglein family and cadherin cell adhesion molecule superfamily of proteins. Desmogleins are calcium-binding transmembrane glycoprotein components of desmosomes, cell-cell junctions between epithelial, myocardial, and other cell types. The encoded preproprotein is proteolytically processed to generate the mature glycoprotein. This gene is present in a gene cluster with other desmoglein gene family members on chromosome 18. Mutations in this gene have been associated with arrhythmogenic right ventricular dysplasia, familial, 10. [provided by RefSeq, Jan 2016]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.796

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000226 (33/1461420) while in subpopulation EAS AF = 0.00053 (21/39626). AF 95% confidence interval is 0.000355. There are 0 homozygotes in GnomAdExome4. There are 13 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
