Genes affected
SLC27A1 (HGNC:10995): (solute carrier family 27 member 1) Enables biotin transmembrane transporter activity; efflux transmembrane transporter activity; and long-chain fatty acid transporter activity. Involved in several processes, including carboxylic acid transmembrane transport; glycerophospholipid biosynthetic process; and lipid transport across blood-brain barrier. Located in membrane. Part of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.1262T>C (p.L421P) alteration is located in exon 8 (coding exon 8) of the SLC27A1 gene. This alteration results from a T to C substitution at nucleotide position 1262, causing the leucine (L) at amino acid position 421 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
