Genes affected

SLC27A4 (HGNC:10998): (solute carrier family 27 member 4) This gene encodes a member of a family of fatty acid transport proteins, which are involved in translocation of long-chain fatty acids cross the plasma membrane. This protein is expressed at high levels on the apical side of mature enterocytes in the small intestine, and appears to be the principal fatty acid transporter in enterocytes. Clinical studies suggest this gene as a candidate gene for the insulin resistance syndrome. Mutations in this gene have been associated with ichthyosis prematurity syndrome.

The c.128G>A (p.R43Q) alteration is located in exon 2 (coding exon 1) of the SLC27A4 gene. This alteration results from a G to A substitution at nucleotide position 128, causing the arginine (R) at amino acid position 43 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
