Congenital anomalies of kidney and urinary tract in siblings: An uncommon condition

Area of Science:

• Pediatric Nephrology
• Clinical Genetics
• Urology

Background:

• Congenital anomalies of kidney and urinary tract (CAKUT) are a leading cause of chronic kidney disease (CKD) in children.
• While often sporadic, familial CAKUT cases highlight potential genetic underpinnings.
• The impact of childhood CKD is substantial, particularly in developing countries.

Observation:

• Two families were identified with siblings affected by CAKUT.
• Affected siblings presented with both upper and lower urinary tract obstruction.
• This familial occurrence underscores the genetic component in some CAKUT cases.

Findings:

• The study documents familial CAKUT in two sibling pairs.
• Both upper and lower urinary tract obstruction were observed in affected siblings.
• This familial pattern suggests a possible inherited predisposition to CAKUT.

Implications:

• Identifying familial CAKUT is crucial for genetic counseling and early intervention.
• Understanding genetic factors in CAKUT can inform future diagnostic and therapeutic strategies.
• Addressing the burden of CAKUT in developing countries requires targeted support and research.
