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 GeneticsSep 20, 2023The c.1055C>T (p.A352V) alteration is located in exon 7 (coding exon 7) of the SLC27A1 gene. This alteration results from a C to T substitution at nucleotide position 1055, causing the alanine (A) at amino acid position 352 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
