Focal Segmental Glomerulosclerosis Panel

The autosomal recessive (AR) form of FSGS is present when a child receives two copies of a defective NPHS2 gene, one from each parent. Any person with one copy of the defective NPHS2 gene is a carrier. Carriers do not have, and will not develop, FSGS. However, if two carriers wish to have children, there is a one in four chance (25%) that their baby will develop FSGS. There is a three in four chance (75%) that their baby will not have AR FSGS. The autosomal dominant (AD) form of FSGS is present when an individual has one copy of the defective TRPC6 or ACTN4 gene. Affected individuals have a 50% chance of transmitting the disorder to each child. There is a 50% chance that the affected individual’s offspring will not be affected with FSGS. Mutations in CD2AP have been reported showing both autosomal recessive and autosomal dominant inheritance patterns.
