Genes affected

NCAPD2 (HGNC:24305): (non-SMC condensin I complex subunit D2) Enables histone binding activity. Involved in mitotic chromosome condensation. Located in condensed chromosome; cytosol; and nucleoplasm. Part of condensin complex. Colocalizes with cytoplasm and nuclear chromosome. Implicated in primary autosomal recessive microcephaly. [provided by Alliance of Genome Resources, Apr 2022]
