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]

The c.211G>C (p.V71L) alteration is located in exon 2 (coding exon 2) of the IDI1 gene. This alteration results from a G to C substitution at nucleotide position 211, causing the valine (V) at amino acid position 71 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
