Mutations in STAG2 cause an X‐linked cohesinopathy associated with undergrowth developmental delay and dysmorphia: Expanding the phenotype in males

摘要

BackgroundThe cohesin complex is a multi‐subunit protein complex which regulates sister chromatid cohesion and separation during cellular division. In addition, this evolutionarily conserved protein complex plays an integral role in DNA replication, DNA repair, and the regulation of transcription. The core complex is composed of four subunits: RAD21, SMC1A, SMC3, and STAG1/2. Mutations in these proteins have been implicated in human developmental disorders collectively termed “cohesinopathies.”
