Genes affected

NCAPH (HGNC:1112): (non-SMC condensin I complex subunit H) This gene encodes a member of the barr gene family and a regulatory subunit of the condensin complex. This complex is required for the conversion of interphase chromatin into condensed chromosomes. The protein encoded by this gene is associated with mitotic chromosomes, except during the early phase of chromosome condensation. During interphase, the protein has a distinct punctate nucleolar localization. Alternatively spliced transcript variants encoding different proteins have been described.

Ambry Genetics

Jul 30, 2024

The c.196C>G (p.Q66E) alteration is located in exon 2 (coding exon 2) of the NCAPH gene. This alteration results from a C to G substitution at nucleotide position 196, causing the glutamine (Q) at amino acid position 66 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
