Genetic Variant TMEM116:p.Val283Ala (chr12-111931787-A-G) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001193531.2(TMEM116):c.848T>C(p.Val283Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00000316 in 1,582,616 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 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. V283G) has been classified as Uncertain significance.
