Dominantly-inherited polycystic kidneys in infants: association with hypertrophic pyloric stenosis
Insights
This study reports a rare family association between dominantly inherited polycystic kidneys and hypertrophic pyloric stenosis. The co-occurrence in twins and their father suggests a potential genetic link, though chance remains a possibility.
Area of Science:
- Medical Genetics
- Pediatric Nephrology
- Gastroenterology
Background:
- Polycystic kidney disease (PKD) is a genetic disorder.
- Hypertrophic pyloric stenosis (HPS) is a common congenital anomaly affecting the stomach outlet.
- Dominantly inherited polycystic kidneys (DPK) are a specific form of PKD.
Observation:
- Newborn fraternal twins presented with bilateral flank masses and diagnosed with polycystic kidney disease.
- Both twins also exhibited symptoms of hypertrophic pyloric stenosis.
- The twins' father had undiagnosed polycystic kidneys and a personal history of hypertrophic pyloric stenosis.
Findings:
- The family displayed a co-occurrence of DPK and HPS across two generations.
- While the association may be coincidental, the study explores a potential genetic overlap.
- The authors hypothesize that the gene for DPK might be located near loci influencing HPS polygenic inheritance.
Implications:
- This case highlights a potential, albeit rare, genetic connection between DPK and HPS.
- Further research may elucidate shared genetic pathways or predispositions.
- Understanding such associations can aid in genetic counseling and early diagnosis for affected families.
Abstract:
Newborn male fraternal twins presented at 10 days of age will bilateral flank masses; intravenous urograms showed polycystic kidney disease. Both babies also had hypertrophic pyloric stenosis (HPS). Their father has radiographic and sonographi findings of previously unsuspected polycystic kidneys and has a history of HPS in infancy. The association of dominantly-inherited polycystic kidneys (DPK) and HPS in this family is probably due to chance. However the authors speculate that the autosomal gene for DPK may occur at one of several loci that carry the genetic liability for HPS, A DISORDER TRANSMITTED BY POLYGENIC INHERITANCE.
