Genes affected

PCDH17 (HGNC:14267): (protocadherin 17) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein contains six extracellular cadherin domains, a transmembrane domain, and a cytoplasmic tail differing from those of the classical cadherins. The encoded protein may play a role in the establishment and function of specific cell-cell connections in the brain. [provided by RefSeq, Jul 2008]

The c.440C>T (p.P147L) alteration is located in exon 1 (coding exon 1) of the PCDH17 gene. This alteration results from a C to T substitution at nucleotide position 440, causing the proline (P) at amino acid position 147 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
