Genes affected

LIPT2 (HGNC:37216): (lipoyl(octanoyl) transferase 2) This gene encodes a mitochondrial protein that catalyzes the transfer of octanoic acid to lipoate-dependent enzymes such as octanoyl-ACP. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2016]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BP6: Variant 11-74492270-C-G is Benign according to our data. Variant chr11-74492270-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 1464621.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.565 with no splicing effect.
