Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2 BP4

The NM_001193531.2(TMEM116):​c.176A>G​(p.Asp59Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000145 in 1,383,384 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. D59V) has been classified as Uncertain significance.
