Genes affected

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]

TICRR links:

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]

The c.3440C>G (p.P1147R) alteration is located in exon 20 (coding exon 20) of the TICRR gene. This alteration results from a C to G substitution at nucleotide position 3440, causing the proline (P) at amino acid position 1147 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
