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.491C>T (p.T164I) alteration is located in exon 2 (coding exon 2) of the LIPT2 gene. This alteration results from a C to T substitution at nucleotide position 491, causing the threonine (T) at amino acid position 164 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
