Entrez Gene Summary for MCPH1 Gene

  • This gene encodes a DNA damage response protein. The encoded protein may play a role in G2/M checkpoint arrest via maintenance of inhibitory phosphorylation of cyclin-dependent kinase 1. Mutations in this gene have been associated with primary autosomal recessive microcephaly 1 and premature chromosome condensation syndrome. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2010]

  • Q8NEM0
  • BRCT domain 1 is required to prevent abnormal chromosome condensation. It binds directly to the SWI-SNF chromatin remodeling complex (PubMed:19925808).
  • BRCT domains 2 and 3 recognize phosphoserine/phosphothreonine marks on proteins with high selectivity, and mediate interaction with phosphorylated CDC27. They also mediate the dual recognition of phosphoserine and phosphotyrosine in the C-terminal tail of histone H2AFX (PubMed:22139841, PubMed:22908299 and PubMed:22908299)
  • Contains 3 BRCT domains.

Disorders for MCPH1 Gene

(1) OMIM Diseases for MCPH1 Gene (607117)


  • Microcephaly 1, primary, autosomal recessive (MCPH1) [MIM:251200]: A disease defined as a head circumference more than 3 standard deviations below the age-related mean. Brain weight is markedly reduced and the cerebral cortex is disproportionately small. Despite this marked reduction in size, the gyral pattern is relatively well preserved, with no major abnormality in cortical architecture. Affected individuals are mentally retarded. Primary microcephaly is further defined by the absence of other syndromic features or significant neurological deficits due to degenerative brain disorder. Some MCHP1 patients also present growth retardation, short stature, and misregulated chromosome condensation as indicated by a high number of prophase-like cells detected in routine cytogenetic preparations and poor-quality metaphase G-banding. {ECO:0000269 PubMed:12046007, ECO:0000269 PubMed:15199523, ECO:0000269 PubMed:16211557}. Note=The disease is caused by mutations affecting the gene represented in this entry.
