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 GeneticsMay 25, 2022The c.1854A>C (p.L618F) alteration is located in exon 12 (coding exon 11) of the CDH19 gene. This alteration results from a A to C substitution at nucleotide position 1854, causing the leucine (L) at amino acid position 618 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
