Genetic Variant NM_022493.3:c.1093G>A (chr16-730942-C-T) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_022493.3(CIAO3):c.1093G>A(p.Ala365Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000311 in 1,612,980 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A365S) has been classified as Uncertain significance.

Genes affected

CIAO3 (HGNC:14179): (cytosolic iron-sulfur assembly component 3) Predicted to enable 4 iron, 4 sulfur cluster binding activity. Involved in several processes, including iron-sulfur cluster assembly; oxygen homeostasis; and response to hypoxia. Part of CIA complex. [provided by Alliance of Genome Resources, Apr 2022]

CIAO3 links:

HAGHL (HGNC:14177): (hydroxyacylglutathione hydrolase like) Predicted to enable hydroxyacylglutathione hydrolase activity and metal ion binding activity. Predicted to be involved in methylglyoxal catabolic process to D-lactate via S-lactoyl-glutathione. [provided by Alliance of Genome Resources, Apr 2022]
