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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.668C>T (p.T223I) 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 668, causing the threonine (T) at amino acid position 223 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
