Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_001265577.2(KIF18B):​c.877G>T​(p.Asp293Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000000686 in 1,457,668 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 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. D293N) has been classified as Uncertain significance.
