Genes affected

UFSP1 (HGNC:33821): (UFM1 specific peptidase 1 (inactive)) This gene encodes a protein that is similar to other Ufm1-specific proteases. Studies in mouse determined that Ufsp1 releases Ufm1 (ubiquitin-fold modifier 1) from its bound conjugated complexes which also makes it into an active form. Because the human UFSP1 protein is shorter on the N-terminus and lacks a conserved Cys active site, it is predicted to be non-functional.[provided by RefSeq, Nov 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16581422).

Collection Method: clinical testing

The c.259G>A (p.V87I) alteration is located in exon 1 (coding exon 1) of the UFSP1 gene. This alteration results from a G to A substitution at nucleotide position 259, causing the valine (V) at amino acid position 87 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
