Genes affected

KIF7 (HGNC:30497): (kinesin family member 7) This gene encodes a cilia-associated protein belonging to the kinesin family. This protein plays a role in the sonic hedgehog (SHH) signaling pathway through the regulation of GLI transcription factors. It functions as a negative regulator of the SHH pathway by preventing inappropriate activation of GLI2 in the absence of ligand, and as a positive regulator by preventing the processing of GLI3 into its repressor form. Mutations in this gene have been associated with various ciliopathies. [provided by RefSeq, Oct 2011]

TICRR (HGNC:28704): (TOPBP1 interacting checkpoint and replication regulator) Enables chromatin binding activity. Involved in regulation of DNA-dependent DNA replication initiation. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 15-89628804-G-C is Benign according to our data. Variant chr15-89628804-G-C is described in ClinVar as Likely_benign. ClinVar VariationId is 3717052.Status of the report is criteria_provided_single_submitter, 1 stars.
