Genes affected

NCAPH2 (HGNC:25071): (non-SMC condensin II complex subunit H2) This gene encodes one of the non-SMC subunits of the condensin II complex. This complex plays an essential role in mitotic chromosome assembly. Alternate splicing of this gene results in multiple transcript variants.[provided by RefSeq, May 2010]

The c.332C>T (p.P111L) alteration is located in exon 4 (coding exon 4) of the NCAPH2 gene. This alteration results from a C to T substitution at nucleotide position 332, causing the proline (P) at amino acid position 111 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
