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.

The c.2081C>T (p.P694L) alteration is located in exon 7 (coding exon 7) of the EHHADH gene. This alteration results from a C to T substitution at nucleotide position 2081, causing the proline (P) at amino acid position 694 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The EHHADH c.2081C>T variant is predicted to result in the amino acid substitution p.Pro694Leu. This variant along with another PKD1 variant, p.Thr938Met (phase unknown), were reported in an individual with polycystic kidney disease ( Zacchia et al. 2021. Table 1 Patient K56 PubMed ID: 33964006). This variant is reported in 0.0078% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-184910105-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
