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]

Collection Method: clinical testing

The c.277G>A (p.G93S) alteration is located in exon 1 (coding exon 1) of the LIPT2 gene. This alteration results from a G to A substitution at nucleotide position 277, causing the glycine (G) at amino acid position 93 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
