• rs773937558
• NM_001167856.3:c.3260T>C

Variant summary

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

The NM_001167856.3(SBNO1):​c.3260T>C​(p.Val1087Ala) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. 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. V1087G) has been classified as Uncertain significance.
