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]

The c.1340A>G (p.N447S) alteration is located in exon 9 (coding exon 8) of the CDH19 gene. This alteration results from a A to G substitution at nucleotide position 1340, causing the asparagine (N) at amino acid position 447 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
