Any syndromic disease caused by a mutation in the NHLRC2 gene and is characterized by severe progressive cerebropulmonary symptoms, resulting in death in infancy from respiratory failure. Features include malabsorption, progressive growth failure, recurrent infections, chronic hemolytic anemia, and transient liver dysfunction.
Features include always present findings: Strabismus, Dystonia, Enlarged liver (hepatomegaly), and Motor delay and others; and common findings: Seizure, Enlarged heart (cardiomegaly), and Microvesicular hepatic steatosis. 42 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Blood and immune system | 7 | Decreased mean corpuscular volume, Recurrent infections, Increased immature red blood cells (reticulocytosis) |
NHLRC2 encodes NHL repeat containing 2 (726 aa). Required for normal embryonic development Highest expression in Cervix Ectocervix (17.4 TPM) and Ovary (17.1 TPM).
Fibrosis, neurodegeneration, and cerebral angiomatosis is associated with mutations in the NHLRC2 gene on chromosome 10.
NHLRC2 is classified as a druggable target with score 0.0.
Genetic testing for NHLRC2 is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for fibrosis, neurodegeneration, and cerebral angiomatosis has been reported in the published literature.
Phenotype severity distribution: 30 always present features, 3 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for fibrosis, neurodegeneration, and cerebral angiomatosis.
114 publications have been identified in PubMed for fibrosis, neurodegeneration, and cerebral angiomatosis. Research spans Review / Meta-Analysis (37%), Case Report / Case Series (36%), and Epidemiology / Natural History (9%).
