Associated with Microcephaly 23 in OMIM and a possible gene for microcephaly in G2P.
PMID: 27737959 (2016) - A homozygous missense variant in NCAPH (c.728C>T, p.Pro243Leu) was detected in a 42-year-old male with microcephaly (OFC -4.2 SD) and moderate ID. Functional studies indicated that although the variant did not affect cellular protein levels, it disrupted condensin-dependent mitotic chromosome integrity, providing supporting evidence for pathogenicity. Biallelic variants in other genes encoding subunits of the two condensin complexes result in a similar phenotype.
