Genes affected

PACS1 (HGNC:30032): (phosphofurin acidic cluster sorting protein 1) This gene encodes a protein with a putative role in the localization of trans-Golgi network (TGN) membrane proteins. Mouse and rat homologs have been identified and studies of the homologous rat protein indicate a role in directing TGN localization of furin by binding to the protease's phosphorylated cytosolic domain. In addition, the human protein plays a role in HIV-1 Nef-mediated downregulation of cell surface MHC-I molecules to the TGN, thereby enabling HIV-1 to escape immune surveillance.

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, PACS1
• BP4: Computational evidence support a benign effect (MetaRNN=0.04151699).

The c.89A>C (p.Q30P) alteration is located in exon 1 (coding exon 1) of the PACS1 gene. This alteration results from a A to C substitution at nucleotide position 89, causing the glutamine (Q) at amino acid position 30 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
