Nager syndrome is a rare condition that mainly affects the development of the face, hands, and arms. Children with Nager syndrome are born with underdeveloped cheek bones (malar hypoplasia) and a very small lower jaw (micrognathia). Children with this condition share many of the problems of those with Treacher Collins syndrome. It is distinguished by flat cheeks, down-slanting eyes, almost total absence of eyelashes, low-set, cup-shaped ears, and a very small lower jaw. Children with the condition also have underdeveloped thumbs and forearms and may have genitourinary abnormalities or heart problems.
