Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001142782.2(MAGI3):​c.275G>C​(p.Arg92Pro) 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. R92L) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MAGI3 NM_001142782.2 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 6.44
