Spectrum of renal involvement among children with ectodermal dysplasia: a case report and narrative review

Area of Science:

• Genetics
• Developmental Biology
• Nephrology

Background:

• Ectodermal dysplasias (EDs) are a diverse group of genetic disorders impacting ectodermal derivatives.
• A recent case highlighted a potential association between ED and congenital renal absence.
• This prompted an investigation into EDs and associated renal abnormalities.

Purpose of the Study:

• To review and consolidate the current understanding of renal anomalies in patients with Ectodermal Dysplasias.
• To explore the spectrum of kidney, ureter, and bladder involvement in ED.
• To inform the development of a refined ED classification system integrating genotype-phenotype data.

Main Methods:

• Comprehensive literature review of studies reporting renal anomalies in Ectodermal Dysplasias.
• Analysis of reported cases detailing kidney, ureter, and bladder abnormalities in ED patients.
• Synthesis of findings to identify patterns and associations.

Main Results:

• Renal anomalies are a notable, potentially underrecognized feature of Ectodermal Dysplasias.
• Reported anomalies include congenital nephrotic syndrome, hypoplastic kidneys, vesicoureteral reflux, and hydronephrosis.
• The spectrum of renal involvement is broad, affecting kidneys, ureters, and bladder.

Conclusions:

• There is a significant association between Ectodermal Dysplasias and a range of renal anomalies.
• Integrating genotype-phenotype correlations is crucial for a refined ED classification.
• A multidisciplinary approach is essential for effective ED management, considering renal involvement.
