Genes affected

SLC27A6 (HGNC:11000): (solute carrier family 27 member 6) This gene encodes a member of the fatty acid transport protein family (FATP). FATPs are involved in the uptake of long-chain fatty acids and have unique expression patterns. Alternatively spliced transcript variants encoding the same protein have been found for this gene.

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.065377325).

The c.128G>A (p.R43Q) alteration is located in exon 1 (coding exon 1) of the SLC27A6 gene. This alteration results from a G to A substitution at nucleotide position 128, causing the arginine (R) at amino acid position 43 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
