Deaths and mortality; More data. Nephrotic syndrome usually occurs when the glomeruli get damaged and fail to properly filter a person's blood. But a few days ago our world changed. Once the GRIN1 pathogenic variants have been identified in an affected family member, prenatal and preimplantation genetic testing are possible. In the year 2005, Down Syndrome life expectancy had risen to a more respectable 49 years. Growth. The life expectancy of people with Beckwith-Wiedemann syndrome (BWS) is generally normal, but it can depend on the specific symptoms and complications that a person experiences.
