Renal hypoplasia

MONDO:0019637

Renal hypoplasia is a developmental anomaly in which one or both kidneys (unilateral or bilateral renal hypoplasia, respectively) have a deficit in the number of nephrons and may be small. Oligomeganephronia represents a severe variant of hypoplasia in which nephron number is reduced by 80% and nephrons are markedly hypertrophied.

Scientists hunt for genes behind rare kidney condition

Knowledge-focused Completed

This study looked at how often kidney hypodysplasia (a condition where one or both kidneys are small and underdeveloped) runs in families. Researchers collected DNA from 342 children aged 3 months to 18 years to try to find genes that may cause the condition. The goal was to bett…
