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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.4306C>T (p.R1436W) alteration is located in exon 33 (coding exon 33) of the NCAPD3 gene. This alteration results from a C to T substitution at nucleotide position 4306, causing the arginine (R) at amino acid position 1436 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
