Noonan syndrome
a genetic disorder that involves the skin, heart, gonads, and skeleton and is transmitted as an autosomal dominant trait. Affected individuals often have short stature, cardiovascular defects, and deafness. Intellectual development varies: Some have above-average intelligence, and most have normal intelligence, but a small percentage have special educational needs or intellectual disability. Male patients are seldom fertile. Also called familial Turner syndrome; Ullrich–Noonan syndrome. [reported in 1963 by Jacqueline Noonan (1928– ), U.S. pediatrician]
