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 GeneticsJul 06, 2021The c.408G>T (p.Q136H) alteration is located in exon 1 (coding exon 1) of the PCDH17 gene. This alteration results from a G to T substitution at nucleotide position 408, causing the glutamine (Q) at amino acid position 136 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
