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]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0287 (2550/89002) while in subpopulation NFE AF= 0.038 (1605/42218). AF 95% confidence interval is 0.0365. There are 648 homozygotes in gnomad4. There are 1097 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 2550 AD gene.
