Genes affected

NCAPG (HGNC:24304): (non-SMC condensin I complex subunit G) This gene encodes a subunit of the condensin complex, which is responsible for the condensation and stabilization of chromosomes during mitosis and meiosis. Phosphorylation of the encoded protein activates the condensin complex. There are pseudogenes for this gene on chromosomes 8 and 15. Alternative splicing results in multiple transcript variants.

The c.743T>C (p.M248T) alteration is located in exon 5 (coding exon 5) of the NCAPG gene. This alteration results from a T to C substitution at nucleotide position 743, causing the methionine (M) at amino acid position 248 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
