Genes affected
IDI1 (HGNC:5387): (isopentenyl-diphosphate delta isomerase 1) IDI1 encodes a peroxisomally-localized enzyme that catalyzes the interconversion of isopentenyl diphosphate (IPP) to its highly electrophilic isomer, dimethylallyl diphosphate (DMAPP), which are the substrates for the successive reaction that results in the synthesis of farnesyl diphosphate and, ultimately, cholesterol. It has been shown in peroxisomal deficiency diseases such as Zellweger syndrome and neonatal adrenoleukodystrophy that there is reduction in IPP isomerase activity. [provided by RefSeq, Jul 2008]
IDI2-AS1 (HGNC:30885): (IDI2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2023The c.462G>C (p.E154D) alteration is located in exon 4 (coding exon 4) of the IDI1 gene. This alteration results from a G to C substitution at nucleotide position 462, causing the glutamic acid (E) at amino acid position 154 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
