Genes affected

CDH11 (HGNC:1750): (cadherin 11) This gene encodes a type II classical cadherin from the cadherin superfamily, integral membrane proteins that mediate calcium-dependent cell-cell adhesion. Mature cadherin proteins are composed of a large N-terminal extracellular domain, a single membrane-spanning domain, and a small, highly conserved C-terminal cytoplasmic domain. Type II (atypical) cadherins are defined based on their lack of a HAV cell adhesion recognition sequence specific to type I cadherins. Expression of this particular cadherin in osteoblastic cell lines, and its upregulation during differentiation, suggests a specific function in bone development and maintenance.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAdExome4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0516 is higher than 0.05.

Review Status: criteria provided, single submitter

Collection Method: research

VUS in a strongly conserved region in the CDH11 gene, which encodes a member of a superfamily of cadherins. A dysregulation of these type of cadherins is thought to be involved in Elsahy-Waters Syndrome, which sometimes presents with craniofacial clefts, including cleft palate, as well as in Teebi hypertelorism syndrome. -
