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]

This sequence change creates a premature translational stop signal (p.Arg154*) in the KIF7 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in KIF7 are known to be pathogenic (PMID: 19666503, 21552264, 21633164, 26648833). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with clinical features of KIF7-related conditions (PMID: 21552264). ClinVar contains an entry for this variant (Variation ID: 30896). For these reasons, this variant has been classified as Pathogenic. -
