Genes affected

CEP350 (HGNC:24238): (centrosomal protein 350) The product of this gene is a large protein with a CAP-Gly domain typically found in cytoskeleton-associated proteins. The encoded protein primarily localizes to the centrosome, a non-membraneous organelle that functions as the major microtubule-organizing center in animal cells. The encoded protein directly interacts with another large centrosomal protein and is required to anchor microtubules at the centrosome. It is also implicated in the regulation of a class of nuclear hormone receptors in the nucleus. Several alternatively spliced transcript variants have been found, but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

The c.80T>C (p.I27T) alteration is located in exon 3 (coding exon 2) of the CEP350 gene. This alteration results from a T to C substitution at nucleotide position 80, causing the isoleucine (I) at amino acid position 27 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
