Genes affected

PCYOX1 (HGNC:20588): (prenylcysteine oxidase 1) Prenylcysteine is released during the degradation of prenylated proteins. PCYOX1 catalyzes the degradation of prenylcysteine to yield free cysteines and a hydrophobic isoprenoid product (Tschantz et al., 1999 [PubMed 10585463]).[supplied by OMIM, Mar 2008]

Jun 29, 2023

The c.430C>T (p.R144C) alteration is located in exon 3 (coding exon 3) of the PCYOX1 gene. This alteration results from a C to T substitution at nucleotide position 430, causing the arginine (R) at amino acid position 144 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
