Introduction to Disease⁚ Renal Hepatic Pancreatic Dysplasia Dandy Walker Cyst
Ivemark et al. first described sibs with renal-hepatic-pancreatic dysplasia (RHPD) (Ivemark BI, Oldfelt V, Zetterström R (1959)⁚ Acta Pediatr Scand 48⁚1-11). Subsequent reports of affected… malformations seen in RHPD we argue that RHPD-DW is a distinct monogenetic syndrome٫ and not an association.(source)
Overview of the Rare Syndrome
Ivemark et al. first described sibs with renal-hepatic-pancreatic dysplasia (RHPD). Subsequent reports detailed additional malformations associated with RHPD, including cases associated with Dandy-Walker cyst. The presence of renal, hepatic, and pancreatic abnormalities characterizes this syndrome.
Goldston et al. reported neonates with cystic renal dysplasia and Dandy-Walker malformation, while Kudo et al. documented cases with Dandy-Walker malformation, congenital hepatic fibrosis, and cystic dysplastic kidneys. RHPD-DW is proposed as a distinct monogenetic syndrome, not just an association.
The Renal-Hepatic-Pancreatic dysplasia syndrome presents a triad of pancreatic fibrosis, renal dysplasia, and hepatic dysgenesis. Several cases have been reported with genetic associations and distinct features, emphasizing the complex nature of this rare syndrome.
NPHP3-related Meckel-like syndrome, a genetic disorder, displays cystic renal dysplasia, central nervous system abnormalities like Dandy-Walker malformation, congenital hepatic fibrosis, and an absence of polydactyly. The syndrome exhibits a unique combination of renal, hepatic, and pancreatic anomalies.
Understanding Renal Hepatic Pancreatic Dysplasia
Ivemark et al. first described sibs with renal-hepatic-pancreatic dysplasia, detailing malformations associated with this syndrome. Goldston et al. reported neonates with cystic renal dysplasia and Dandy-Walker malformation, linking these conditions.
Characteristics and Historical Discoveries
The renal-hepatic-pancreatic dysplasia syndrome was first described by Ivemark et al. in 1959, detailing a triad of pancreatic fibrosis, renal dysplasia, and hepatic dysgenesis. Subsequent reports linked this syndrome with a range of malformations, including cases with Dandy-Walker cyst.
Goldston et al. documented neonates with cystic renal dysplasia and Dandy-Walker malformation. Kudo et al. reported cases with Dandy-Walker malformation, congenital hepatic fibrosis, and cystic dysplastic kidneys. These findings underscore the complexity and genetic associations of this rare syndrome.
Inherited as an autosomal recessive disorder, NPHP3-related Meckel-like syndrome presents with cystic renal dysplasia, Dandy-Walker malformation, hepatic fibrosis, and an absence of polydactyly, showcasing unique combinations of renal, hepatic, and pancreatic abnormalities.
Studies report cases with individuals displaying skeletal and central nervous system anomalies alongside mutations like NPHP3. The distinct features of dysplasia in the kidney, pancreas, and liver, and the absence of neural defects are indicative of Renal-Hepatic-Pancreatic dysplasia syndrome.
Clinical Presentation and Associated Malformations
The renal-hepatic-pancreatic dysplasia (RHPD) presents with a triad of pancreatic fibrosis, renal dysplasia, and hepatic dysgenesis. Reports have linked RHPD with Dandy-Walker cyst, Jeune syndrome, trisomy 9, Saldino-Noonan syndrome, and Elejalde types among others. Cases often feature various skeletal and central nervous system anomalies, highlighting the complexity of this condition.
Genetic studies have identified mutations such as NPHP3 related to Meckel-like syndrome, showing characteristics like cystic renal dysplasia, Dandy-Walker malformation, hepatic fibrosis, and a lack of polydactyly. The absence of neural defects and the presence of renal, hepatic, and pancreatic dysplasia aid in distinguishing the Renal-Hepatic-Pancreatic dysplasia syndrome from other conditions like Dandy-Walker cyst and ARPKD.
Research indicates a monogenetic nature for the RHPD-DW subtype, implying a distinct genetic syndrome rather than an association of malformations. The presence of characteristic features like dysplasia in key organs along with the absence of polydactyly supports the diagnosis of the complex Renal-Hepatic-Pancreatic Dysplasia syndrome.
Exploring Dandy Walker Cyst
Dandy-Walker Cyst is often associated with Renal-Hepatic-Pancreatic dysplasia. Genetic studies highlight distinctive features of neural defects in DW, while this genetic disorder shares similarities with Meckel syndrome like renal malformations and hepatic abnormalities. The presence of cystic renal disease and neural anomalies defines the diverse spectrum of this complex disorder.
Link to Renal Hepatic Pancreatic Dysplasia
The unique association between Dandy-Walker Cyst and Renal-Hepatic-Pancreatic Dysplasia has been documented in various studies. The syndrome encompasses a complex interplay of genetic factors, leading to a distinct monogenetic syndrome rather than a simple association. The presence of renal, hepatic, and pancreatic dysplasia alongside neural defects like Dandy-Walker Cyst distinguishes this syndrome from other conditions. Genetic mutations such as NPHP3 have been linked to Meckel-like syndrome, further emphasizing the intricate genetic landscape of this rare disorder.
Distinct Features and Genetic Associations
In genetic studies, renal-hepatic-pancreatic dysplasia (RHPD) has been linked to notable features like neural defects in Dandy-Walker cyst. This genetic disorder has similarities with Meckel syndrome, involving renal malformations and hepatic abnormalities. The presence of cystic renal disease and various neural anomalies defines the diverse spectrum of this multifaceted disorder.
Furthermore, the distinct characteristics of dysplasia in kidneys, pancreas, and liver, along with the absence of neural defects, contribute to identifying the Renal-Hepatic-Pancreatic dysplasia syndrome. Research indicates a monogenetic basis for the RHPD-DW subtype, emphasizing a genetic syndrome rather than a mere grouping of malformations. Genetic mutations such as NPHP3 have been associated with a Meckel-like syndrome, shedding light on the intricate genetic underpinnings of this rare condition.
