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]

Acrocallosal syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 13, 2022This variant, c.3986_3997del, results in the deletion of 4 amino acid(s) of the KIF7 protein (p.Arg1329_Ser1332del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs780942335, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with KIF7-related conditions. ClinVar contains an entry for this variant (Variation ID: 30902). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
