Genetic Variant TUSC2:p.Pro42His (chr3-50327975-G-T) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_007275.3(TUSC2):c.125C>A(p.Pro42His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000713 in 1,542,962 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P42R) has been classified as Uncertain significance.

Genes affected

TUSC2 (HGNC:17034): (tumor suppressor 2, mitochondrial calcium regulator) Predicted to be involved in inflammatory response and regulation of mitochondrial membrane potential. Predicted to act upstream of or within several processes, including natural killer cell differentiation; neutrophil-mediated killing of gram-negative bacterium; and regulation of cytokine production. Predicted to be active in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
