Study Overview

Status

Conditions

Detailed Description

DNA collection from the propositus and its family. A questionnaire will be filled by the parents to seek other affected individual in the family.With another affected member, DNA collection will be collected from the whole family.

A renal ultrasound will be prescribed for the parents, brothers and sisters.
