Genes affected

PCDH9 (HGNC:8661): (protocadherin 9) This gene encodes a member of the protocadherin family, and cadherin superfamily, of transmembrane proteins containing cadherin domains. These proteins mediate cell adhesion in neural tissues in the presence of calcium. The encoded protein may be involved in signaling at neuronal synaptic junctions. Sharing a characteristic with other protocadherin genes, this gene has a notably large exon that encodes multiple cadherin domains and a transmembrane region. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Nov 2012]

The c.3361G>C (p.G1121R) alteration is located in exon 5 (coding exon 4) of the PCDH9 gene. This alteration results from a G to C substitution at nucleotide position 3361, causing the glycine (G) at amino acid position 1121 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
