Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001363830.2(SLFN12L):​c.692A>T​(p.Glu231Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E231K) has been classified as Uncertain significance.

The c.620A>T (p.E207V) alteration is located in exon 2 (coding exon 2) of the SLFN12L gene. This alteration results from a A to T substitution at nucleotide position 620, causing the glutamic acid (E) at amino acid position 207 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
