Insights
Hardikar syndrome (HS) is a rare disorder with multiple anomalies. This report details a new patient with HS, including novel features and the need for liver transplantation, suggesting a potential genetic link to Alagille syndrome.
Area of Science:
- Genetics and rare diseases
- Pediatric medicine
- Medical case reports
Background:
- Hardikar syndrome (HS) is a rare genetic disorder characterized by multiple congenital anomalies.
- Previous reports documented a specific constellation of symptoms including cleft lip/palate, liver and biliary tract disease, intestinal malrotation, obstructive uropathy, and retinopathy.
- Only three patients with chronic liver/biliary disease and organogenesis defects had been previously described.
Observation:
- This report presents a fourth patient diagnosed with Hardikar syndrome.
- The patient exhibited previously unreported features such as vaginal atresia and a type 1 choledochal cyst.
- Progressive liver disease necessitated liver transplantation in this patient.
Findings:
- The addition of a new patient expands the known clinical spectrum of Hardikar syndrome.
- The identification of novel features refines the diagnostic criteria and understanding of HS.
- The case highlights the severe progression of liver disease in HS and the potential need for advanced interventions like liver transplantation.
Implications:
- This case study contributes valuable data to the limited literature on Hardikar syndrome.
- The findings suggest a possible genetic overlap or relationship between Hardikar syndrome and Alagille syndrome due to shared phenotypic abnormalities.
- Further research into the genetic underpinnings of HS is warranted to elucidate its etiology and relationship with similar conditions.
Abstract:
Hardikar syndrome (HS) is a disorder of multiple anomalies predominantly characterized by cleft lip/palate, liver and biliary tract disease, intestinal malrotation, obstructive uropathy, and retinopathy. To date, three patients have been reported with the unusual constellation of chronic liver/biliary tract disease and obvious defects in organogenesis [Hardikar et al. (1992): Am J Med Genet 44: 13-17; Cools and Jaeken (1997): Am J Med Genet 71: 472-474]. With this report, we add another patient with this syndrome. New features, hitherto not reported, were vaginal atresia, a type 1 choledochal cyst and, owing to the progressive nature of the liver disease, the need for liver transplantation. It is intriguing to speculate, that HS could be genetically related to Alagille syndrome (AS), since both conditions share an unusual number of phenotypic abnormalities.
