Genes affected

ECI2 (HGNC:14601): (enoyl-CoA delta isomerase 2) 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, Aug 2011]

The c.409A>G (p.T137A) alteration is located in exon 4 (coding exon 4) of the ECI2 gene. This alteration results from a A to G substitution at nucleotide position 409, causing the threonine (T) at amino acid position 137 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
