Genes affected

ELOVL3 (HGNC:18047): (ELOVL fatty acid elongase 3) This gene encodes a protein that belongs to the GNS1/SUR4 family. Members of this family play a role in elongation of long chain fatty acids to provide precursors for synthesis of sphingolipids and ceramides. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.937

The c.450C>A (p.S150R) alteration is located in exon 4 (coding exon 4) of the ELOVL3 gene. This alteration results from a C to A substitution at nucleotide position 450, causing the serine (S) at amino acid position 150 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
