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 GeneticsJan 03, 2024The c.1258C>G (p.R420G) alteration is located in exon 8 (coding exon 8) of the SLC27A1 gene. This alteration results from a C to G substitution at nucleotide position 1258, causing the arginine (R) at amino acid position 420 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
