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.

Variant classified as Uncertain Significance - Favor Benign. The p.Pro4Arg varia nt in HSD17B4 has not been previously reported in individuals with hearing loss, bi-functional protein deficiency (BPD), or Perrault syndrome. It has been ident ified in 36/126190 European by the Genome Aggregation Database (gnomAD, http://g nomad.broadinstitute.org; dbSNP rs142889209). Although this variant has been see n in the general population, its frequency is not high enough to rule out a path ogenic role. Computational prediction tools suggest that the p.Pro4Arg variant m ay not impact the protein, though this information is not predictive enough to r ule out pathogenicity. In summary, the clinical significance of the p.Pro4Arg va riant is uncertain. -

Collection Method:clinical testing

The c.11C>G (p.P4R) alteration is located in exon 1 (coding exon 1) of the HSD17B4 gene. This alteration results from a C to G substitution at nucleotide position 11, causing the proline (P) at amino acid position 4 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
