• chr1-1455485-G-T
• rs747061326
• NM_001039211.3:c.404G>T

Variant summary

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

The NM_001039211.3(ATAD3C):​c.404G>T​(p.Arg135Leu) 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. R135Q) has been classified as Uncertain significance.
