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]

Collection Method: clinical testing

The c.191G>C (p.G64A) alteration is located in exon 1 (coding exon 1) of the UFSP1 gene. This alteration results from a G to C substitution at nucleotide position 191, causing the glycine (G) at amino acid position 64 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
