Genes affected

EHHADH (HGNC:3247): (enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase) The protein encoded by this gene is a bifunctional enzyme and is one of the four enzymes of the peroxisomal beta-oxidation pathway. The N-terminal region of the encoded protein contains enoyl-CoA hydratase activity while the C-terminal region contains 3-hydroxyacyl-CoA dehydrogenase activity. Defects in this gene are a cause of peroxisomal disorders such as Zellweger syndrome. Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0153059065).
• BP6: Variant 3-185192281-T-A is Benign according to our data. Variant chr3-185192281-T-A is described in ClinVar as [Benign]. Clinvar id is 501352.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-185192281-T-A is described in Lovd as [Benign].
• BS2: High AC in GnomAd4 at 646 AD gene.
