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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2023The c.475C>G (p.P159A) alteration is located in exon 1 (coding exon 1) of the PCDH17 gene. This alteration results from a C to G substitution at nucleotide position 475, causing the proline (P) at amino acid position 159 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
