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 Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PACS1. . Gene score misZ 3.71 (greater than the threshold 3.09). Trascript score misZ 3.8723 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, Schuurs-Hoeijmakers syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.07175964).
