Genes affected

CDH9 (HGNC:1768): (cadherin 9) 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. The extracellular domain consists of 5 subdomains, each containing a cadherin motif, and appears to determine the specificity of the protein's homophilic cell adhesion activity. Type II (atypical) cadherins are defined based on their lack of a HAV cell adhesion recognition sequence specific to type I cadherins. [provided by RefSeq, Jul 2008]

Jan 26, 2022

The c.2318G>A (p.R773H) alteration is located in exon 12 (coding exon 11) of the CDH9 gene. This alteration results from a G to A substitution at nucleotide position 2318, causing the arginine (R) at amino acid position 773 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
