Genes affected

CEP295 (HGNC:29366): (centrosomal protein 295) Enables microtubule binding activity. Involved in several processes, including centriole replication; positive regulation of protein acetylation; and regulation of centrosome duplication. Located in cytosol; microtubule cytoskeleton; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.7772C>G (p.T2591R) alteration is located in exon 30 (coding exon 29) of the CEP295 gene. This alteration results from a C to G substitution at nucleotide position 7772, causing the threonine (T) at amino acid position 2591 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
