Genes affected

PSD (HGNC:9507): (pleckstrin and Sec7 domain containing) This gene encodes a Plekstrin homology and SEC7 domains-containing protein that functions as a guanine nucleotide exchange factor. The encoded protein regulates signal transduction by activating ADP-ribosylation factor 6. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

PSD (HGNC:):

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.
