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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.148C>G (p.P50A) 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 148, causing the proline (P) at amino acid position 50 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
