Genes affected
IFT57 (HGNC:17367): (intraflagellar transport 57) Predicted to enable DNA binding activity. Acts upstream of or within activation of cysteine-type endopeptidase activity involved in apoptotic process; apoptotic process; and regulation of apoptotic process. Predicted to be located in ciliary basal body. Predicted to be part of axoneme and intraciliary transport particle B. Predicted to be active in Golgi apparatus; centrosome; and cilium. Implicated in orofaciodigital syndrome. [provided by Alliance of Genome Resources, Apr 2022]
