Genes affected

KIAA0753 (HGNC:29110): (KIAA0753) This gene encodes a subunit of a protein complex that regulates ciliogenesis and cilia maintenance. The encoded protein has also been shown to regulate centriolar duplication. Mutations in this gene cause an orofaciodigital syndrome and a form of Joubert syndrome in human patients.

The c.2863G>C (p.E955Q) alteration is located in exon 19 (coding exon 18) of the KIAA0753 gene. This alteration results from a G to C substitution at nucleotide position 2863, causing the glutamic acid (E) at amino acid position 955 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
