Mietens syndrome is a autosomal recessive disorder first described by Mietens and Weber. [3] The condition is named after a German physician named Carl Mietens. [4]
Only 9 cases have been reported. [5]
In 1966, Carl Mietens and Helge Weber reported cases of four children, 3 sisters and 1 brother. Who suffered from a cluster of congenital anomalies and mental retardantion. [8]
In 2006, two documented has been reported. [9]
Adducted thumb syndrome recessive form is a rare disease affecting multiple systems causing malformations of the palate, thumbs, and upper limbs. The name Christian syndrome derives from Joe. C. Christian, the first person to describe the condition. Inheritance is believed to be autosomal recessive, caused by mutation in the CHST14 gene.
Lucey–Driscoll syndrome is an autosomal recessive metabolic disorder affecting enzymes involved in bilirubin metabolism. It is one of several disorders classified as a transient familial neonatal unconjugated hyperbilirubinemia.
Nezelof syndrome is an autosomal recessive congenital immunodeficiency condition due to underdevelopment of the thymus. The defect is a type of purine nucleoside phosphorylase deficiency with inactive phosphorylase, this results in an accumulation of deoxy-GTP which inhibits ribonucleotide reductase. Ribonucleotide reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides, thus, DNA replication is inhibited.
Duane-radial ray syndrome, also known as Okihiro syndrome, is a rare autosomal dominant disorder that primarily affects the eyes and causes abnormalities of bones in the arms and hands. This disorder is considered to be a SALL4-related disorder due to the SALL4 gene mutations leading to these abnormalities. It is diagnosed by clinical findings on a physical exam as well as genetic testing and imaging. After being diagnosed, there are other evaluations that one may go through in order to determine the extent of the disease. There are various treatments for the symptoms of this disorder.
SCARF syndrome is a rare syndrome characterized by skeletal abnormalities, cutis laxa, craniostenosis, ambiguous genitalia, psychomotor retardation, and facial abnormalities. These characteristics are what make up the acronym SCARF. It shares some features with Lenz-Majewski hyperostotic dwarfism. It is a very rare disease with an incidence rate of approximately one in a million newborns. It has been clinically described in two males who were maternal cousins, as well as a 3-month-old female. Babies affected by this syndrome tend to have very loose skin, giving them an elderly facial appearance. Possible complications include dyspnea, abdominal hernia, heart disorders, joint disorders, and dislocations of multiple joints. It is believed that this disease's inheritance is X-linked recessive.
Kaufman oculocerebrofacial syndrome, also known as blepharophimosis-ptosis-intellectual disability syndrome, is an extremely rare autosomal recessive congenital disorder characterized by severe mental retardation, brachycephaly, upslanting palpebral fissures, eye abnormalities, and highly arched palate. It was characterized in 1971; eight cases had been identified as of 1995. To date, the amount of cases is disputed, with sources claiming the number ranges from 14 to 31.
Gray platelet syndrome (GPS), or platelet alpha-granule deficiency, is a rare congenital autosomal recessive bleeding disorder caused by a reduction or absence of alpha-granules in blood platelets, and the release of proteins normally contained in these granules into the marrow, causing myelofibrosis. The name derives from the initial observation of gray appearance of platelets with a paucity of granules on blood films from a patient with a lifelong bleeding disorder.
Atransferrinemia is an autosomal recessive metabolic disorder in which there is an absence of transferrin, a plasma protein that transports iron through the blood. Atransferrinemia is characterized by anemia and hemosiderosis in the heart and liver. The iron damage to the heart can lead to heart failure. The anemia is typically microcytic and hypochromic. Atransferrinemia was first described in 1961 and is extremely rare, with only ten documented cases worldwide.
Schinzel–Giedion syndrome (SGS) is a congenital neurodegenerative terminal syndrome. It was first described in 1978 by Albert Schinzel (1944–) and Andreas Giedion (1925–) as a syndrome with severe midface retraction, skull anomalies, renal anomalies (hydronephrosis) and other anomalies. Babies born with Schinzel–Giedion syndrome have severe mental retardation, growth retardation and global developmental delay.
Marden–Walker syndrome (MWS) is a rare autosomal recessive congenital disorder. It is characterized by blepharophimosis, microcephaly, micrognathia, multiple joint contractures, arachnodactyly, camptodactyly, kyphoscoliosis and delayed motor development and is often associated with cystic dysplastic kidneys, dextrocardia, Dandy–Walker malformation and agenesis of corpus callosum.
Majeed syndrome is an inherited skin disorder characterized by chronic recurrent multifocal osteomyelitis, congenital dyserythropoietic anemia and a neutrophilic dermatosis. It is classified as an autoinflammatory bone disorder. The condition is found in people with two defective copies of the LPIN2 gene. LPIN2 encodes lipin-2 which is involved in lipid metabolism. The pathogenesis of this mutation with the clinical manifestations has not been elucidated.
Alopecia contractures dwarfism intellectual disability syndrome or is a developmental disorder which causes mainly baldness and dwarfism in combination with intellectual disability; skeletal anomalies, caries and nearsightedness are also typical.
Lyngstadaas syndrome, also known as severe dental aberrations in familial steroid dehydrogenase deficiency, is a rare autosomal recessive liver disease involving an enzyme deficiency and dental anomalies. The disease is named after the Norwegian professor Ståle Petter Lyngstadaas.
Gordon syndrome, or distal arthrogryposis type 3, is a rare genetic disorder characterized by cleft palate and congenital contractures of the hands and feet.
Heart-hand syndromes are a group of rare diseases that manifest with both heart and limb deformities.
Radioulnar synostosis is a rare condition where there is an abnormal connection (synostosis) between the radius and ulna bones of the forearm. This can be present at birth (congenital), when it is a result of a failure of the bones to form separately, or following an injury (post-traumatic).
Juberg–Hayward syndrome is a rare genetic syndrome characterised by cleft lip and cleft palate, microcephaly, ptosis, short stature, hypoplasia or aplasia of thumbs, dislocation of radial head and fusion of humerus and radius. The abnormalities in the arm lead to restriction of movement in the elbow.
Microcephaly albinism digital anomalies syndrome is a very rare congenital genetic disease. The syndrome includes microcephaly, micrognathia, oculocutaneous albinism, hypoplasia of the distal phalanx of fingers, and agenesia of the distal end of the right big toe.
Blepharophimosis-ptosis-esotropia-syndactyly-short stature syndrome is a very rare genetic and congenital disorder which is characterized by blepharophimosis, ptosis, V-esotropia, foot syndactyly, extra-ocular and frontal muscles weakness, low height/short stature, prognathism, and synophrys.
Cardiocranial syndrome, Pfeiffer type is a rare multiple disorder syndrome characterized by congenital heart defects, sagittal craniosynostosis, and severe developmental delay. The condition has been reported in less than 10 patients worldwide.
