SRP54 function has not been fully characterized.
Neutropenia, severe congenital, 8, autosomal dominant is associated with mutations in the SRP54 gene on chromosome 14.
Genetic testing for SRP54 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 3 always present features, 5 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
1 clinical trial registered, 1 recruiting. Interventions under study include other interventions. Research is primarily sponsored by academic and government institutions.
3 publications have been identified in PubMed for neutropenia, severe congenital, 8, autosomal dominant. Kisho has analyzed 2 by research type. Research spans Review / Meta-Analysis (100%).
