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.

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the SLC27A4 protein in which other variant(s) (p.Arg51His) have been observed in individuals with SLC27A4-related conditions (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. Disruption of the initiator codon has been observed in individual(s) with ichthyosis prematurity syndrome (PMID: 21690550, 34720920). This variant is present in population databases (rs142366975, gnomAD 0.01%). This sequence change affects the initiator methionine of the SLC27A4 mRNA. The next in-frame methionine is located at codon 133. -
