Genes affected
CDH22 (HGNC:13251): (cadherin 22) This gene is a member of the cadherin superfamily. The gene product is composed of five cadherin repeat domains and a cytoplasmic tail similar to the highly conserved cytoplasmic region of classical cadherins. Expressed predominantly in the brain, this putative calcium-dependent cell adhesion protein may play an important role in morphogenesis and tissue formation in neural and non-neural cells during development and maintenance of the brain and neuroendocrine organs.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2022The c.2453G>T (p.G818V) alteration is located in exon 11 (coding exon 11) of the CDH22 gene. This alteration results from a G to T substitution at nucleotide position 2453, causing the glycine (G) at amino acid position 818 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
