Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001394531.1(WDFY4):​c.497T>G​(p.Leu166Arg) 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 pathogenic 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. L166Q) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 31)

The c.497T>G (p.L166R) alteration is located in exon 5 (coding exon 4) of the WDFY4 gene. This alteration results from a T to G substitution at nucleotide position 497, causing the leucine (L) at amino acid position 166 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
