In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 33)
• Consequence: PSD3 NM_015310.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.73

Genes affected

PSD3 (HGNC:19093): (pleckstrin and Sec7 domain containing 3) Predicted to enable guanyl-nucleotide exchange factor activity and phospholipid binding activity. Predicted to be involved in regulation of ARF protein signal transduction and regulation of catalytic activity. Predicted to be located in membrane. Predicted to be active in ruffle membrane.
