Genes affected
CEP152 (HGNC:29298): (centrosomal protein 152) This gene encodes a protein that is thought to be involved with centrosome function. Mutations in this gene have been associated with primary microcephaly (MCPH4). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

The c.2090A>G (p.H697R) alteration is located in exon 16 (coding exon 15) of the CEP152 gene. This alteration results from a A to G substitution at nucleotide position 2090, causing the histidine (H) at amino acid position 697 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
