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]

Ambry Genetics

Nov 10, 2024

The c.3269G>A (p.R1090H) alteration is located in exon 19 (coding exon 19) of the TICRR gene. This alteration results from a G to A substitution at nucleotide position 3269, causing the arginine (R) at amino acid position 1090 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
