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]
TEX56P (HGNC:21620): (testis expressed 56, pseudogene)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.895A>G (p.M299V) alteration is located in exon 9 (coding exon 9) of the ECI2 gene. This alteration results from a A to G substitution at nucleotide position 895, causing the methionine (M) at amino acid position 299 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
