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.3683C>T (p.T1228M) alteration is located in exon 30 (coding exon 30) of the USP40 gene. This alteration results from a C to T substitution at nucleotide position 3683, causing the threonine (T) at amino acid position 1228 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
