Genes affected

USP40 (HGNC:20069): (ubiquitin specific peptidase 40) Modification of cellular proteins by ubiquitin is an essential regulatory mechanism controlled by the coordinated action of multiple ubiquitin-conjugating and deubiquitinating enzymes. USP40 belongs to a large family of cysteine proteases that function as deubiquitinating enzymes (Quesada et al., 2004 [PubMed 14715245]).[supplied by OMIM, Mar 2008]

The c.3681G>C (p.E1227D) alteration is located in exon 30 (coding exon 30) of the USP40 gene. This alteration results from a G to C substitution at nucleotide position 3681, causing the glutamic acid (E) at amino acid position 1227 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
