Infantile hypertrophic pyloric stenosis--unusual familial incidence
Insights
A man with a history of infantile hypertrophic pyloric stenosis (PS) had three sons also diagnosed with PS. This suggests a strong genetic component, with family history indicating inherited predispositions to the condition.
Area of Science:
- Medical Genetics
- Pediatric Surgery
Background:
- Infantile hypertrophic pyloric stenosis (PS) is a congenital condition affecting newborns.
- Family history is a known risk factor for developing PS.
Purpose of the Study:
- To investigate the potential genetic transmission of infantile hypertrophic pyloric stenosis (PS).
- To analyze a family's history of PS to understand inheritance patterns.
Main Methods:
- A case study of a male patient with PS and his offspring.
- Construction of a family genealogical table to trace the incidence of PS.
Main Results:
- The proband, treated for PS, had three sons diagnosed with the same condition.
- The proband's parents had relatives with a history of PS.
- No known family history of PS was reported on the wife's side.
Conclusions:
- The findings suggest that genes predisposing to infantile hypertrophic pyloric stenosis (PS) were carried by the man's parents.
- These genes were transmitted to the man, who subsequently passed them to all his children, leading to the high incidence of PS in his offspring.
Abstract:
A man, who had been treated for infantile hypertrophic pyloric stenosis (PS), was found to have 3 sons with the same condition. A genealogical table of his family showed that both his parents had relatives with PS. So far as it was known, none of his wife's relatives had the condition. It is suggested that the man's parents carried genes predisposing to PS and transmitted these to him in such quantity that he and all his children acquired the condition.
