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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.1457A>G (p.Q486R) 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 1457, causing the glutamine (Q) at amino acid position 486 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
