• chr3-43347659-T-G

Variant summary

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

The NM_017719.5(SNRK):​c.1400T>G​(p.Leu467Trp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. L467V) has been classified as Uncertain significance.

The c.1400T>G (p.L467W) alteration is located in exon 7 (coding exon 5) of the SNRK gene. This alteration results from a T to G substitution at nucleotide position 1400, causing the leucine (L) at amino acid position 467 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
