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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.1862G>A (p.R621Q) alteration is located in exon 12 (coding exon 11) of the CDH19 gene. This alteration results from a G to A substitution at nucleotide position 1862, causing the arginine (R) at amino acid position 621 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
