Genes affected

HACD2 (HGNC:9640): (3-hydroxyacyl-CoA dehydratase 2) The protein encoded by this gene can catalyze the third step (dehydration) in the conversion of long chain fatty acids to very long chain fatty acids. The encoded protein localizes to the endoplasmic reticulum membrane. [provided by RefSeq, Jul 2016]

The c.740C>A (p.T247N) alteration is located in exon 7 (coding exon 7) of the HACD2 gene. This alteration results from a C to A substitution at nucleotide position 740, causing the threonine (T) at amino acid position 247 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
