Features include always present findings: Systolic heart murmur, Ventricular septal defect, and Elevated creatinine (kidney function marker) (elevated circulating creatinine concentration); and common findings: Truncus arteriosus, Generalized edema, Partial agenesis of the corpus callosum, and Cyanosis. 23 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Heart and blood vessels | 5 | Interrupted aortic arch, Systolic heart murmur, Ventricular septal defect |
TMEM260 function has not been fully characterized.
Structural heart defects and renal anomalies syndrome is associated with mutations in the TMEM260 gene on chromosome 14.
Genetic testing for TMEM260 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 3 always present features, 4 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for structural heart defects and renal anomalies syndrome.
4 publications have been identified in PubMed for structural heart defects and renal anomalies syndrome. Research spans Basic Science / Preclinical (75%) and Case Report / Case Series (25%).
