Genes affected

NCAPD3 (HGNC:28952): (non-SMC condensin II complex subunit D3) Condensin complexes I and II play essential roles in mitotic chromosome assembly and segregation. Both condensins contain 2 invariant structural maintenance of chromosome (SMC) subunits, SMC2 (MIM 605576) and SMC4 (MIM 605575), but they contain different sets of non-SMC subunits. NCAPD3 is 1 of 3 non-SMC subunits that define condensin II (Ono et al., 2003 [PubMed 14532007]).[supplied by OMIM, Mar 2008]

The c.4426G>A (p.A1476T) alteration is located in exon 35 (coding exon 35) of the NCAPD3 gene. This alteration results from a G to A substitution at nucleotide position 4426, causing the alanine (A) at amino acid position 1476 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
