Glomuvenous malformations (GVMs) are hereditary vascular malformations characterized by the presence of small, multifocal bluish-purple venous lesions involving the skin.
Features include very common findings: Venous malformation and Arteriovenous malformation; and common findings: Abnormal digit morphology and Skin nodule. 18 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Skin | 7 | Abnormality of the skin, Skin nodule, Generalized abnormality of skin |
GLMN encodes glomulin, FKBP associated protein (594 aa). Regulatory component of cullin-RING-based SCF (SKP1-Cullin-F-box protein) E3 ubiquitin-protein ligase complexes. Highest expression in Brain Cerebellar Hemisphere (20.3 TPM) and Cells EBV-transformed lymphocytes (16.9 TPM).
Glomuvenous malformation is associated with mutations in the GLMN gene on chromosome 1.
GLMN is classified as a druggable target (Enzyme category) with score 0.0.
Genetic testing for GLMN is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 2 very common features, 2 common features.
Estimated prevalence: Unknown (Unknown prevalence).
No clinical trials have been registered for glomuvenous malformation.
21 publications have been identified in PubMed for glomuvenous malformation. Research spans Case Report / Case Series (62%), Review / Meta-Analysis (19%), and Other (14%).
