Genes affected

SKA2 (HGNC:28006): (spindle and kinetochore associated complex subunit 2) Enables microtubule binding activity. Involved in several processes, including chromosome segregation; mitotic cell cycle; and regulation of microtubule polymerization or depolymerization. Located in spindle microtubule. Part of outer kinetochore. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000224738 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
