Genes affected

ZFR (HGNC:17277): (zinc finger RNA binding protein) This gene encodes an RNA-binding protein characterized by its DZF (domain associated with zinc fingers) domain. The encoded protein may play a role in the nucleocytoplasmic shuttling of another RNA-binding protein, Staufen homolog 2, in neurons. Expression of this gene is regulated through alternative polyadenylation that mediates differential microRNA targeting. Elevated expression of this gene has been observed in human patients with pancreatic cancer and knockdown of this gene may result in reduced viability and invasion of pancreatic cancer cells.

ACMG classification

Verdict is Uncertain_significance. Variant got 3 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), ZFR. . Gene score misZ 4.0921 (greater than the threshold 3.09). Trascript score misZ 4.7998 (greater than threshold 3.09). GenCC has associacion of gene with hereditary spastic paraplegia, autosomal recessive spastic paraplegia type 71.
