Genes affected

KIAA0586 (HGNC:19960): (KIAA0586) This gene encodes a conserved centrosomal protein that functions in ciliogenesis and responds to hedgehog signaling. Mutations in this gene causes Joubert syndrome 23. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Aug 2016]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).

The KIAA0586 c.9+10T>C variant is predicted to interfere with splicing. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. However, the use of computer prediction programs is not equivalent to functional evidence, and therefore the clinical significance of this variant is uncertain. -
