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.935C>T (p.A312V) alteration is located in exon 4 (coding exon 1) of the USP49 gene. This alteration results from a C to T substitution at nucleotide position 935, causing the alanine (A) at amino acid position 312 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
