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 -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0045408607).
• BP6: Variant 3-185192290-G-A is Benign according to our data. Variant chr3-185192290-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 774610.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=2}.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0123 (18002/1461864) while in subpopulation MID AF= 0.0182 (105/5766). AF 95% confidence interval is 0.0154. There are 132 homozygotes in gnomad4_exome. There are 8951 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1283 AD gene.
