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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.2770G>A (p.A924T) alteration is located in exon 16 (coding exon 15) of the PSD gene. This alteration results from a G to A substitution at nucleotide position 2770, causing the alanine (A) at amino acid position 924 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
