Prognosis for Holoprosencephaly
Prognosis for Holoprosencephaly: The prognosis for individuals with the disorder is poor. Most of those who survive show no significant developmental gains. (Source: excerpt from NINDS Holoprosencephaly Information Page: NINDS)

Article Excerpts about Holoprosencephaly
Holoprosencephaly is a disorder caused by the failure of the prosencephalon (the forebrain of the embryo) to divide to form bilateral cerebral hemispheres, causing defects in the development of the face and in brain structure and function. Once called arhinencephaly, the disorder consists of a spectrum of defects or malformations of the brain and face. (Source: excerpt from NINDS Holoprosencephaly Information Page: NINDS)
Definitions of Holoprosencephaly:
Anterior midline brain, cranial, and facial malformations resulting from the failure of the embryonic prosencephalon to undergo segmentation and cleavage. Alobar prosencephaly is the most severe form and features anophthalmia; cyclopia; severe MENTAL RETARDATION; CLEFT LIP; CLEFT PALATE; SEIZURES; and microcephaly. Semilobar holoprosencepaly is characterized by hypotelorism, microphthalmia, coloboma, nasal malformations, and variable degrees of mental retardation. Lobar holoprosencephaly is associated with mild (or absent) facial malformations and intellectual abilities that range from mild mental retardation to normal. Holoprosencephaly is associated with CHROMOSOME ABNORMALITIES. - (Source - Diseases Database)
Holoprosencephaly is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Holoprosencephaly, or a subtype of Holoprosencephaly,
affects less than 200,000 people in the US population.
Source - National Institutes of Health (NIH)
Ophanet, a consortium of European partners,
currently defines a condition rare when it affects 1 person per 2,000.
They list Holoprosencephaly as a "rare disease".
