Genes affected

CDH19 (HGNC:1758): (cadherin 19) This gene is one of three related type II cadherin genes situated in a cluster on chromosome 18. The encoded protein is a calcium dependent cell-cell adhesion glycoprotein containing five extracellular cadherin repeats. Loss of cadherins may be associated with cancer formation. Alternative splicing results in multiple transcript variants for this gene. [provided by RefSeq, Aug 2012]

Feb 16, 2023

The c.1631C>T (p.P544L) alteration is located in exon 11 (coding exon 10) of the CDH19 gene. This alteration results from a C to T substitution at nucleotide position 1631, causing the proline (P) at amino acid position 544 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
