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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2023The c.185G>A (p.R62Q) alteration is located in exon 2 (coding exon 2) of the HACD2 gene. This alteration results from a G to A substitution at nucleotide position 185, causing the arginine (R) at amino acid position 62 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
