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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009622633).

BP6

Variant 11-6640369-G-T is Benign according to our data. Variant chr11-6640369-G-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 445814.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00629 (959/152346) while in subpopulation NFE AF = 0.0115 (781/68042). AF 95% confidence interval is 0.0108. There are 6 homozygotes in GnomAd4. There are 424 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 6 AD,AR gene
