Schinzel–Giedion syndrome is a congenitalneurodegenerative terminal syndrome. First described in 1978 by Dr. Albert Schinzel (1944- )and Dr. Andreas Giedion (1925- ) as a syndrome with severe midface retraction, skull anomalies, renal anomalies (hydronephrosis) and other anomalies. Babies born with Schinzel–Giedion syndrome have severe mental retardation, growth retardation (unless fed through a feeding tube) and global developmental delay.
