Genetic Variant ACACB:c.2144+49_2144+72delTTCCTTCCTTCCTTCCTTCCTTCC (chr12-109188171-CTCCTTCCTTCCTTCCTTCCTTCCT-C) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_001093.4(ACACB):c.2144+49_2144+72delTTCCTTCCTTCCTTCCTTCCTTCC variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000265 in 1,357,102 control chromosomes in the GnomAD database, including 2 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

ACACB (HGNC:85): (acetyl-CoA carboxylase beta) Acetyl-CoA carboxylase (ACC) is a complex multifunctional enzyme system. ACC is a biotin-containing enzyme which catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the rate-limiting step in fatty acid synthesis. ACC-beta is thought to control fatty acid oxidation by means of the ability of malonyl-CoA to inhibit carnitine-palmitoyl-CoA transferase I, the rate-limiting step in fatty acid uptake and oxidation by mitochondria. ACC-beta may be involved in the regulation of fatty acid oxidation, rather than fatty acid biosynthesis. [provided by RefSeq, Oct 2022]
