Genes affected

CDH6 (HGNC:1765): (cadherin 6) This gene encodes a member of the cadherin superfamily. Cadherins are membrane glycoproteins that mediate homophilic cell-cell adhesion and play critical roles in cell differentiation and morphogenesis. The encoded protein is a type II cadherin and may play a role in kidney development as well as endometrium and placenta formation. Decreased expression of this gene may be associated with tumor growth and metastasis. [provided by RefSeq, May 2011]

The c.248G>A (p.R83K) alteration is located in exon 3 (coding exon 2) of the CDH6 gene. This alteration results from a G to A substitution at nucleotide position 248, causing the arginine (R) at amino acid position 83 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
