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]
LIPT2-AS1 (HGNC:56172): (LIPT2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.302C>T (p.P101L) alteration is located in exon 1 (coding exon 1) of the LIPT2 gene. This alteration results from a C to T substitution at nucleotide position 302, causing the proline (P) at amino acid position 101 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
