Holoprosencephaly is a serious birth defect in which the front part of the brain, known as the forebrain, fails to form correctly. Recent advancements in genomic knowledge base and powerful analytical methods have helped in identifying several underlying genetic aberrations related with holoprosencephaly but the search is still incomplete. micro/dolichocephaly, high and broad forehead, prominent eyebrows, thick, anteverted ear lobes, short nose with a broad nasal bridge and bulbous tip, prominent philtrum, large mouth with thin upper lip and thick, everted lower lip). Findings. In most cases of holoprosencephaly, the malformations are so severe that babies die before birth. Motor delay and Abnormality of the dentition, related diseases and genetic alterations. Pathogenesis of holoprosencephaly is complex and heterogeneous involving genetic abnormalities, teratogenic exposures, and syndromic associations. Most people with nonsyndromic holoprosencephaly have developmental delay and intellectual disability. Case Images. Affected males who survive have a more severe phenotype than affected females, and sporadic male cases may result from somatic mosaicism (Behninger and Rott, 2000). 7-DHC was not elevated at 1 year of age and SLOS con-sidered excluded at this time. It is more common in stillbirths and miscarriages.

Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A) is an autosomal recessive disorder with characteristic brain and eye malformations, profound mental retardation, and congenital muscular dystrophy. EIEE49 is a severe autosomal recessive neurologic disorder characterized by onset of seizures in the neonatal period, global developmental delay with intellectual disability and lack of speech, hypotonia, spasticity, and coarse facial features. Some patients may have brain calcifications on imaging (summary by Han et al., 2016).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ). Patients with Delayed speech and language development and Holoprosencephaly. Holoprosencephaly can also occur in association with malformations in other organ systems that are not directly related to holoprosencephaly. Osteopathia striata is a frequent feature of focal dermal hypoplasia (FDH ).Although early reports of familial cases of this disorder appeared to suggest autosomal dominant inheritance (see, e.g., Horan and Beighton, 1978 and Konig et al., 1996), reappraisal of the literature (Behninger and Rott, 2000; Rott et al., 2003) and the finding of a molecular basis for the disorder by Jenkins et al. Plastic surgery should be consulted to correct the cleft lip and cleft palate as well as to reconstruct other facial deformities that are part of the holoprosencephaly. The olfactory bulbs and septum pellucidum are absent and the sylvian fissures are poorly formed in all forms.

Holoprosencephaly. HPE has an overall incidence of 1/250 in early fetal loss, but of 1/15 000 ( Bullen et al., 2001 ) at birth. Delayed speech and language development, and Holoprosencephaly Diseases related with Delayed speech and language development and Holoprosencephaly. Osteopathia striata with cranial sclerosis is an X-linked dominant sclerosing bone dysplasia that presents in females with macrocephaly, cleft palate, mild learning disabilities, sclerosis of the long bones and skull, and longitudinal striations visible on radiographs of the long bones, pelvis, and scapulae (Jenkins et al., 2009). Holoprosencephaly (HPE) is a complex brain malformation resulting from incomplete cleavage of the prosencephalon, occurring between the 18th and the 28th day of gestation and affecting both the forebrain and the face. Affected individuals also frequently have a malfunctioning pituitary gland, which is a gland located at the base of the brain that produces several hormones. In less severe cases, babies are born with normal or near-normal brain development and facial deformities that may affect the eyes, nose and upper lip.

Developmental delay is present in all individuals with the holoprosencephaly spectrum of CNS (central nervous system) anomalies. For developmental delays, a specialist in this field of medical science can be of great help in helping the parents and the child. The degree of delay is variable, correlating with the severity of the brain malformation, but tends to be severe. Three ranges of increasing severity are described: lobar, semi-lobar and alobar HPE. Holoprosencephaly is a rare spectrum of cephalic disorders resulting from a failure or incomplete division of the embryonic forebrain into distinct cerebral hemispheres. SCTID It is not a substitute for professional medical advice, diagnosis or treatment. These entities are part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as 'dystroglycanopathies' (Godfrey et al., 2007; Muntoni and Voit, 2004; Muntoni et al., 2008).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ). ... to be consulted for correction of cleft lip and palate and reconstruct other facial deformities that are a part of Holoprosencephaly. Aprosencephaly and atelencephaly occur earlier because of failure in the formation of the prosencephalon and telencephalon, respectively. Diagnosis. The phenotype includes the alternative clinical designation Walker-Warburg syndrome (WWS), which is associated with death in infancy. Monosomy 13q14 is a rare chromosomal anomaly syndrome, resulting from a partial deletion of the long arm of chromosome 13, characterized by developmental delay, variable degrees of intellectual disability, retinoblastoma and craniofacial dysmorphism (incl. Seizures are common, and may be difficult to control. FKTN-related Walker-Warburg syndrome is a more severe manifestation of the disorder, with death usually in the first year of life. Alagille Jagged1 or Notch 2 mutation The result is a single-lobed brain structure and severe skull and facial defects. Babies with any type of holoprosencephaly also may have seizures, water on the brain, neural tube defects, pituitary dysfunction, short height, feeding problems, developmental delay, and intellectual disability. UMLS Holoprosencephaly HPE Developmental Delay Disorders Brain Disorders: Detailed Description: Holoprosencephaly (HPE) is a defect of midline forebrain development that occurs soon after conception.

MONDO Clinical Report Patient AE (BL-901-12) three months old Male with developmental delay and dysmorphic features, was referred from the Genetic Occasional surviving males have, in addition to hyperostosis, cardiac, intestinal, and genitourinary malformations. The severity of the brain malformation determines the degree of delay and neurologic impairments (including hypotonia and spasticity). Among the teratogenic exposures, maternal diabetes is a well-established risk factor associated with a 200-fold increased incidence of holoprosencephaly. ORPHANET. NCIT Virtually all surviving individuals with the more severe forms of holoprosencephaly have some developmental delay, often persisting as mental retardation. q22.3, presented with developmental delay, holoprosencephaly, agenesis of corpus callosum, dysmorphic features, scoliosis and seizures.
