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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 29, 2024The c.3698G>A (p.R1233Q) alteration is located in exon 30 (coding exon 30) of the USP40 gene. This alteration results from a G to A substitution at nucleotide position 3698, causing the arginine (R) at amino acid position 1233 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
