Genes affected
ADHFE1 (HGNC:16354): (alcohol dehydrogenase iron containing 1) The ADHFE1 gene encodes hydroxyacid-oxoacid transhydrogenase (EC 1.1.99.24), which is responsible for the oxidation of 4-hydroxybutyrate in mammalian tissues (Kardon et al., 2006 [PubMed 16616524]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.626T>A (p.I209N) alteration is located in exon 7 (coding exon 7) of the ADHFE1 gene. This alteration results from a T to A substitution at nucleotide position 626, causing the isoleucine (I) at amino acid position 209 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
