Genes affected

CDHR2 (HGNC:18231): (cadherin related family member 2) This gene is a member of the protocadherin family, which represents a subset of the larger cadherin superfamily. The members of the protocadherin family encode non-classical cadherins that function as calcium-dependent cell-cell adhesion molecules. This protocadherin represents a new candidate for tumor suppression. Alternatively spliced transcript variants that encode the same protein have been identified. [provided by RefSeq, Jan 2010]

Collection Method: clinical testing

The c.71C>T (p.P24L) alteration is located in exon 3 (coding exon 2) of the CDHR2 gene. This alteration results from a C to T substitution at nucleotide position 71, causing the proline (P) at amino acid position 24 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
