Thin basement membrane nephropathy

Thin basement membrane nephropathy is an autosomal dominant disorder caused by heterozygous Alport-specific mutations. The haploinsufficiency of collagen 4 genes is responsible for the development of a thin basement membrane and erythrocyturia.

Differentials

When sensorineural deafness and Alport-typical ocular abnormalities develop the disease is called Alport syndrome.

Management

Therapy

It is recommended to control those patients on a regular basis and to commence ACE inhibitor therapy as soon as proteinuria exceeds 300mg/d or other renal risk factors develop.

Couseling

Heterozygous carriers should be aware of the risk af a child with full blown Alport syndrome if mating with an other carrier, Female carriers of an x-linked Alport mutation have a 50% risk of an affected boy.
