Variant summary

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

The NM_012421.4(RLF):​c.758C>T​(p.Ala253Val) variant causes a missense change. The variant allele was found at a frequency of 0.000000709 in 1,410,960 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. A253G) has been classified as Uncertain significance.
