Clinical and genetic profile of Indian children with primary hyperoxaluria
Primary hyperoxaluria (PH) has heterogeneous renal manifestations in infants and children. This often leads to delay in diagnosis. In the past 3 years, genetic samples were sent for seven children with a clinical diagnosis of PH. Their medical records were reviewed for clinical presentation and outc...

Primary hyperoxaluria (PH) has heterogeneous renal manifestations in infants and children. This often leads to delay in diagnosis. In the past 3 years, genetic samples were sent for seven children with a clinical diagnosis of PH. Their medical records were reviewed for clinical presentation and outcomes. Of the seven children, three were males. The median age of presentation was 4.9 years with the youngest presenting at 3 months of age. Nephrolithiasis, the most common presentation was associated with renal dysfunction in two children. Two children with no significant history presented in end-stage renal disease (ESRD). The sibling of one of the children in ESRD, with a history of consanguinity in parents, was screened for asymptomatic nephrolithiasis.
