Genes affected
ACAA2 (HGNC:83): (acetyl-CoA acyltransferase 2) The encoded protein catalyzes the last step of the mitochondrial fatty acid beta-oxidation spiral. Unlike most mitochondrial matrix proteins, it contains a non-cleavable amino-terminal targeting signal. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2023The c.1111C>T (p.R371C) alteration is located in exon 10 (coding exon 10) of the ACAA2 gene. This alteration results from a C to T substitution at nucleotide position 1111, causing the arginine (R) at amino acid position 371 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
