A Study of the Genetic Analysis of Brain Disorders
https://clinicaltrials.gov/ct2/show/NCT00645645

Dec 14th, 2021 - Holoprosencephaly (HPE) covers a nearly continuous spectrum of midline abnormalities ranging from unmistakable cyclopia with absence of forebrain separation to mild microforms, such a single central incisor. The objective of these studies is to id...

Retrospective Study Using Next Generation Sequencing (NGS) on Biological Samples to Improve Genetic Counseling for Patients With Previously Explored Craniofacial Midline Defects.
https://clinicaltrials.gov/ct2/show/NCT04691414

Dec 7th, 2021 - Holoprosencephaly, or HPE, is the most common congenital cerebral malformation in humans and the most severe of a group of pathologies related to a deficiency of the SHH signalling pathway (Sonic Hedgehog SHH-D). It is characterized by severe cere...

Clinical and Genetic Studies on Holoprosencephaly
https://clinicaltrials.gov/ct2/show/NCT00088426

Apr 20th, 2020 - Holoprosencephaly (HPE) is a defect of midline forebrain development that occurs soon after conception. It has a prevalence of 1 in 250 during early embryonic development, and 1 in 10,000 to 1 in 20,000 at term. In live born infants, the abnormali...

Study of the Experiences and Needs of Parents Continuing a Pregnancy Following a Prenatal Diagnosis of Holopresencephaly
https://clinicaltrials.gov/ct2/show/NCT00005016

Mar 4th, 2008 - Holoprosencephaly (HPE) is a condition that when found prenatally offers parents a poor but often uncertain prognosis for their baby. Parents that continue the pregnancy given this diagnosis are left to endure the remainder of the pregnancy and th...
