Genes affected
FAR2 (HGNC:25531): (fatty acyl-CoA reductase 2) This gene belongs to the short chain dehydrogenase/reductase superfamily. It encodes a reductase enzyme involved in the first step of wax biosynthesis wherein fatty acids are converted to fatty alcohols. The encoded peroxisomal protein utilizes saturated fatty acids of 16 or 18 carbons as preferred substrates. Alternatively spliced transcript variants have been observed for this gene. Related pseudogenes have been identified on chromosomes 2, 14 and 22. [provided by RefSeq, Nov 2012]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 10, 2023 | The c.136C>A (p.P46T) alteration is located in exon 2 (coding exon 1) of the FAR2 gene. This alteration results from a C to A substitution at nucleotide position 136, causing the proline (P) at amino acid position 46 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
