Genes affected

ECI1 (HGNC:2703): (enoyl-CoA delta isomerase 1) This gene encodes a member of the hydratase/isomerase superfamily. The protein encoded is a key mitochondrial enzyme involved in beta-oxidation of unsaturated fatty acids. It catalyzes the transformation of 3-cis and 3-trans-enoyl-CoA esters arising during the stepwise degradation of cis-, mono-, and polyunsaturated fatty acids to the 2-trans-enoyl-CoA intermediates. Alternatively spliced transcript variants have been described. [provided by RefSeq, May 2010]

The c.820G>A (p.V274M) alteration is located in exon 7 (coding exon 7) of the ECI1 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the valine (V) at amino acid position 274 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
