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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 11-74491959-G-A is Benign according to our data. Variant chr11-74491959-G-A is described in ClinVar as [Benign]. Clinvar id is 1277061.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.632 is higher than 0.05.
