In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day.

Information on many genetic disorders, and the frequent new findings on them, has been extremely difficult to come by—until now. The “Gale Encyclopedia of Genetic Disorders” addresses the need for current, hard-to-find facts on emerging discoveries. The two-volume Encyclopedia, presented in a single alphabetical sequence, provides clear, complete information on genetic disorders, including conditions, tests, procedures, treatments and therapies, in articles that are both comprehensive and easy to understand, in language accessible to laypersons. The articles are arranged in a standardized format for quick comparison and ease of use, while non-disorder topics are covered in detail with extended entries. Students will want to consult the “Gale Encyclopedia of Genetic Disorders” for useful information on a range of well known disorders, including Down Syndrome, Trisomy, Hemophilia and Tourette Syndrome, and rarely seen diseases such as Meckel Syndrome, Neuraminidase Deficiency and Phenylketonuria.

Cleft lip (cheiloschisis) and cleft palate (palatoschisis) (colloquially known as harelip), which can also occur together as cleft lip and palate, are variations of a type of clefting congenital deformity caused by abnormal facial development during gestation. A cleft is a fissure or opening?a gap. It is the non-fusion of the body's natural structures that form before birth. Clefts can also affect other parts of the face, such as the eyes, ears, nose, cheeks and forehead. In 1976, Dr. Paul Tessier described fifteen lines of cleft. These craniofacial clefts are rare and are frequently described as Tessier clefts using the numerical locator devised by Dr. Tessier. A cleft lip or palate can be successfully treated with surgery soon after birth. Cleft lips or palates occur in somewhere between one in 600-800 births. ... Read more
