Genes affected

CEP72 (HGNC:25547): (centrosomal protein 72) The product of this gene is a member of the leucine-rich-repeat (LRR) superfamily of proteins. The protein is localized to the centrosome, a non-membraneous organelle that functions as the major microtubule-organizing center in animal cells. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.227C>G (p.T76S) alteration is located in exon 3 (coding exon 3) of the CEP72 gene. This alteration results from a C to G substitution at nucleotide position 227, causing the threonine (T) at amino acid position 76 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
