Also known as:MCPH23

Overview

GeneticsAutosomal recessive · NCAPH (chr 2)

ResearchLimited published research (1 article)

Clinical Presentation

Built from Human Phenotype Ontology (HPO) phenotype annotations and GeneReviews clinical descriptions. Features represent findings documented across known cases — not an exhaustive list of possible symptoms.

Features include always present findings: Sloping forehead, Microcephaly, Moderate intellectual disability, and Small for gestational age.

Genetic Landscape

Assembled from HGNC gene records, ClinGen gene-disease validity evidence, and ClinVar pathogenic variant data. Validity classifications reflect the strength of published evidence linking each gene to this disease.

NCAPH encodes non-SMC condensin I complex subunit H (741 aa). Regulatory subunit of the condensin complex, a complex required for conversion of interphase chromatin into mitotic-like condense chromosomes. Highest expression in Cells EBV-transformed lymphocytes (57.6 TPM) and Testis (37.2 TPM).

Microcephaly 23, primary, autosomal recessive is associated with mutations in the NCAPH gene on chromosome 2.

The NCAPH protein participates in Condensation of Prometaphase Chromosomes pathway.

NCAPH is classified as a druggable target with score 0.0.

Diagnosis

Genetic testing for NCAPH is available. Testing is considered confirmatory for diagnosis.

Prognosis

Phenotype severity distribution: 4 always present features.
