• chr3-169767599-C-G
• rs1202342289
• NM_032487.5:c.952G>C

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2 PP3

The NM_032487.5(ACTRT3):​c.952G>C​(p.Ala318Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic 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. A318S) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: ACTRT3 NM_032487.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.16
• Publications: 0 publications found
