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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.538G>A (p.E180K) alteration is located in exon 4 (coding exon 4) of the PCYOX1 gene. This alteration results from a G to A substitution at nucleotide position 538, causing the glutamic acid (E) at amino acid position 180 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
