Genes affected

UFSP2 (HGNC:25640): (UFM1 specific peptidase 2) This gene encodes a highly conserved cysteine protease. The protein cleaves two C-terminal residues from ubiquitin-fold modifier 1, a ubiquitin-like post-translational modifier protein. Activation of ubiquitin-fold modifier 1 by the encoded protein exposes a C-terminal glycine residue that allows interaction with other proteins and transfer to its target protein. An allelic variant of this gene has been associated with Beukes hip dysplasia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.015509248).
• BP6: Variant 4-185408335-C-G is Benign according to our data. Variant chr4-185408335-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 780512.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0127 (1936/152258) while in subpopulation AFR AF= 0.0444 (1846/41532). AF 95% confidence interval is 0.0428. There are 37 homozygotes in gnomad4. There are 896 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1936 AD gene.
