Genes affected

HSD17B4 (HGNC:5213): (hydroxysteroid 17-beta dehydrogenase 4) The protein encoded by this gene is a bifunctional enzyme that is involved in the peroxisomal beta-oxidation pathway for fatty acids. It also acts as a catalyst for the formation of 3-ketoacyl-CoA intermediates from both straight-chain and 2-methyl-branched-chain fatty acids. Defects in this gene that affect the peroxisomal fatty acid beta-oxidation activity are a cause of D-bifunctional protein deficiency (DBPD). An apparent pseudogene of this gene is present on chromosome 8. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Jul 30, 2015

p.Ala19Gly in exon 1A of HSD17B4: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, >20 mammals have a Gly at this position despite high nearby amino acid co nservation. In addition, computational prediction tools do not suggest a high li kelihood of impact to the protein. This variant has also been identified in 3/10 294 of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exa c.broadinstitute.org; dbSNP rs148363262). -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
