Variant summary

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

The NM_080627.4(MTCL2):​c.4408G>T​(p.Gly1470Cys) 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. G1470S) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MTCL2 NM_080627.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 6.05
• Publications: 0 publications found
