Infantile Bartter syndrome with deafness type 4

Infantile Bartter syndrome is an autosomal recessive disease caused either by mutation of the BSND gene or by simultaneous mutation of CLCNKA and CLCNKB genes.

Epidemiology

Although exact figures still unknown and difficult to obtain, the the incidence is thought between 1 in 50,000 to 1 in 100,000.

Symptoms

Deafness
Sensorineural deafness in infantile Bartter syndrome results from endolyphatic electrolyte dysbalance.
Polyhydramnios
Polyhydramnios can be the first, antenatal, Symptom.
