Variant summary

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

The NM_001276380.2(ESF1):​c.1025G>T​(p.Arg342Leu) 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. R342C) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ESF1 NM_001276380.2 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.84
• Publications: 1 publications found
