Genes affected

TOGARAM1 (HGNC:19959): (TOG array regulator of axonemal microtubules 1) Predicted to enable microtubule binding activity. Predicted to be involved in organelle assembly and positive regulation of microtubule polymerization. Predicted to be located in ciliary basal body. Predicted to be active in cilium and microtubule cytoskeleton. Predicted to colocalize with microtubule. Implicated in Joubert syndrome. [provided by Alliance of Genome Resources, Apr 2022]

KLHL28 (HGNC:19741): (kelch like family member 28)

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=-0.77).
