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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.3553G>A (p.D1185N) alteration is located in exon 29 (coding exon 29) of the USP40 gene. This alteration results from a G to A substitution at nucleotide position 3553, causing the aspartic acid (D) at amino acid position 1185 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
