What is a Harlequin baby?
Harlequin ichthyosis is a severe genetic disorder that mainly affects the skin.
The newborn infant is covered with plates of thick skin that crack and split apart.
The thick plates can pull at and distort facial features and can restrict breathing and eating.
Mutations in the ABCA12 gene cause harlequin ichthyosis..
What is the charge Syndrome?
Collapse Section. CHARGE syndrome is a disorder that affects many areas of the body. CHARGE is an abbreviation for several of the features common in the disorder: coloboma, heart defects, atresia choanae (also known as choanal atresia), growth retardation, genital abnormalities, and ear abnormalities.
What is Carpenter’s syndrome?
Carpenter syndrome is a condition characterized by the premature fusion of certain skull bones (craniosynostosis), abnormalities of the fingers and toes, and other developmental problems. Craniosynostosis prevents the skull from growing normally, frequently giving the head a pointed appearance (acrocephaly).
What is Floating Harbor Syndrome?
Floating-Harbor syndrome (FHS) is an extremely rare genetic disorder characterized by a distinctive facial appearance, various skeletal malformations, delayed bone age, and expressive and receptive language delays. Children may be below average height for their age (short stature).
How is Costello Syndrome diagnosed?
Costello syndrome is diagnosed by clinical examination and specific diagnostic criteria have been developed. Molecular genetic testing for mutations in the HRAS gene is available to confirm the diagnosis. Most clinically affected individuals have an identifiable HRAS mutation.
What is Beckman Wiedemann syndrome?
Beckwith-Wiedemann syndrome (BWS) is the most common overgrowth and cancer predisposition disorder. BWS is caused by changes on chromosome 11p15. 5 and is characterized by a wide spectrum of symptoms and physical findings that vary in range and severity from person to person.
What is Hallermann Streiff syndrome?
Hallermann-Streiff syndrome (HSS) is a rare disorder that is primarily characterized by distinctive malformations of the skull and facial (craniofacial) region; sparse hair (hypotrichosis); eye abnormalities; dental defects; degenerative skin changes (atrophy), particularly in the scalp and nasal regions; and …
What causes Costello Syndrome?
Causes. Mutations in the HRAS gene cause Costello syndrome. This gene provides instructions for making a protein called H-Ras, which is part of a pathway that helps control cell growth and division . Mutations that cause Costello syndrome lead to the production of an H-Ras protein that is abnormally turned on (active).
What is Malan syndrome?
Malan syndrome (MIM# 614753; also called as Sotos syndrome 2) is an overgrowth disorder, characterized by overgrowth, an unusual facial phenotype, intellectual disability, and behavioral problems.
Who gets Proteus syndrome?
Overgrowth becomes apparent between the ages of 6 and 18 months and gets more severe with age. In people with Proteus syndrome, the pattern of overgrowth varies greatly but can affect almost any part of the body. Bones in the limbs, skull, and spine are often affected.
Can Proteus syndrome be cured?
There’s no cure for Proteus syndrome. Treatment generally focuses on minimizing and managing symptoms. The condition affects many parts of the body, so your child may need treatment from several doctors, including the following: cardiologist.
Can Sotos syndrome be prevented?
Sotos syndrome causes overgrowth during the early years of a child’s life. Children with Sotos syndrome may have several health problems and require ongoing care. There’s no cure for this genetic disorder, but some of the symptoms can be treated.
What is Greig Cephalopolysyndactyly syndrome?
Greig cephalopolysyndactyly syndrome (GCPS) is a rare genetic disorder characterized by physical abnormalities affecting the fingers and toes (digits) and the head and facial (craniofacial) area.
Can Sotos syndrome be detected before birth?
Prenatal microarrays are currently available that can diagnose microdeletions in the following genomic regions; Sotos (5q35), Beckwith Wiedemann (11p15), and 22q13. A prenatal microarray study may be useful if there is evidence of overgrowth with other abnormalities.
Is Sotos syndrome genetic?
Sotos syndrome is an autosomal dominant genetic condition. Dominant genetic disorders occur when only a single copy of an abnormal variant of a gene is necessary to cause a particular disease.
How common is Legius syndrome?
Summary. Legius syndrome , also known as NF1-like syndrome, is a rare, genetic skin pigmentation disorder characterized by multiple café-au-lait macules with or without axillary or inguinal freckling. The prevalence of Legius syndrome is not known. Fewer than 200 cases have been reported to date.
What is the life expectancy of someone with Sotos syndrome?
Sotos syndrome is not a life-threatening disorder and patients may have a normal life expectancy. The initial abnormalities of Sotos syndrome usually resolve as the growth rate becomes normal after the first few years of life.
What is Proteus syndrome?
Proteus syndrome is a rare disorder characterized by overgrowth of various tissues of the body. The cause of the disorder is a mosaic variant in a gene called AKT1. Disproportionate, asymmetric overgrowth occurs in a mosaic pattern (i.e., a random “patchy” pattern of affected and unaffected areas).
Is Sotos Syndrome a disability?
People with Sotos syndrome often have intellectual disability, and most also have behavioral problems.
What is Kabuki syndrome?
Kabuki syndrome is a rare genetic disorder with a range of characteristics, including intellectual disability, distinctive facial features and skeletal abnormalities. There is no cure – treatment aims to reduce the risk of complications and improve quality of life.
