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.

This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 15 of the SLC27A4 protein (p.Lys15Arg). This variant is present in population databases (rs774441905, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with SLC27A4-related conditions. ClinVar contains an entry for this variant (Variation ID: 1485135). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
