Genetic Variant KIF26B:p.Asp1904Tyr (chr1-245688693-G-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 4P and 4B. PM5PP3_ModerateBS2

The NM_018012.4(KIF26B):c.5710G>T(p.Asp1904Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000747 in 1,606,602 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. D1904N) has been classified as Likely pathogenic.

Genes affected

KIF26B (HGNC:25484): (kinesin family member 26B) The protein encoded by this gene is an intracellular motor protein thought to transport organelles along microtubules. The encoded protein is required for kidney development. Elevated levels of this protein have been found in some breast and colorectal cancers. [provided by RefSeq, Mar 2017]
