Genes affected

USP49 (HGNC:20078): (ubiquitin specific peptidase 49) Enables cysteine-type endopeptidase activity; histone binding activity; and thiol-dependent deubiquitinase. Involved in histone H2B conserved C-terminal lysine deubiquitination and mRNA splicing, via spliceosome. Predicted to be located in nucleoplasm. Predicted to be active in cytoplasm.

The c.716C>G (p.T239R) alteration is located in exon 4 (coding exon 1) of the USP49 gene. This alteration results from a C to G substitution at nucleotide position 716, causing the threonine (T) at amino acid position 239 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
