A non-syndromic, microcytic/hypochromic sideroblastic anaemia, present from early infancy and characterised by severe microcytic anaemia, which is not pyridoxine responsive, and increased serum ferritin. To date, fewer than 30 unrelated genetically characterised individuals have been reported. Clinical features are those of anaemia and iron overload and include pallor, fatigue, weakness, breathlessness, splenomegaly, hyperglycaemia, glucose intolerance and skin hyperpigmentation. Patients need blood transfusions to survive and do not respond to treatment with pyridoxine. Caused by a homozygous or compound heterozygous mutation in the SLC25A38 gene located on chromosome 3p22.1. The SLC25A38 gene mutation is transmitted as an autosomal recessive trait.

Affected neonates are stillborn or die rapidly after birth. Craniofacial dysmorphism has characteristics of prominent forehead, hypertelorism, a depressed nasal bridge with a grooved tip, micrognathia and frequently a cleft palate. There is a continuum with overlapping clinical findings between atelosteogenesis I, atelosteogenesis III and boomerang dysplasia. This disease results from heterozygous mutations in exons 2-5 and 27-33 of the gene encoding filamin B (FLNB) located to 3p14.	Outdated component (foundation metadata concept)
A permanent thyroid deficiency that is present from birth, characterised by low levels of thyroid hormones caused by disorders in the development or function of the pituitary. The clinical manifestations can be subtle, probably as a result of trans-placental passage of some maternal thyroid hormone or due to the fact that many infants have some thyroid production of their own. Goitre is always absent. Slow linear growth and developmental delay are usually apparent by 4-6 months of age. Without treatment hypothyroidism results in severe intellectual deficit and short stature. The hypothyroidism is caused by mutations in genes regulating pituitary gland development including HESX1, LHX3, LHX4, POU1F1 and PROP1 (3p21.2-p21.1, 9q34.3, 1q25, 3p11 and 5q).

A primary glomerular disease with characteristics of proteinuria, type IV renal tubular acidosis, microscopic haematuria and hypertension that may lead to end-stage renal failure in the second to sixth decade of life. Fibronectin glomerulopathy may present at different ages, although mostly in adolescence or early adulthood, with typical features of a nephrotic syndrome including hypertension. Clustering of the disease within families indicates a genetic origin. In 40% of families, the disease is caused by heterozygous mutations in the FN1 gene (2q34) encoding fibronectin. Whole-genome linkage analysis in a large pedigree showed another disease locus on 1q32, however no specific candidate genes has been identified so far. Segregation with disease appearance in successive generations is consistent with an autosomal dominant pattern of inheritance with age-related penetrance.

A rare X-linked genetic epilepsy syndrome affecting females. The syndrome has characteristics of seizures starting in the first years of life and intellectual disability and may resemble Dravet syndrome. In families with this disease, male carriers are unaffected despite the X-linked inheritance.	Outdated component (foundation metadata concept)
A rare X-linked genomic disorder associated with interstitial chromosomal duplications at Xq28 encompassing the MECP2 gene. In males the disease has characteristics of infantile onset hypotonia, severe global developmental delay, intellectual disability, progressive spasticity, seizures, gastrointestinal symptoms and recurrent respiratory infections. In females, the phenotype is more variable. The syndrome is due to Xq28 duplications (< 4 Mb) involving the dosage-sensitive gene MECP2. The pattern of inheritance is X-linked. The recurrence risk is significant if the duplication encompassing the MECP2 gene is inherited from the mother, but very low if the duplication is de novo. There is full disease penetrance in males and variable penetrance in females due to the level and type of X-inactivation.	Outdated component (foundation metadata concept)

A rare X-linked syndromic intellectual disability disease with characteristics of neonatal hypertonia which evolves to hypotonia and an exaggerated startle response (to sudden visual, auditory or tactile stimuli), followed by the development of early-onset, frequently refractory, tonic or myoclonic seizures. Progressive epileptic encephalopathy, intellectual disability, and psychomotor development arrest, with subsequent decline, may be additionally associated. There is the disease is caused by mutation in the ARHGEF9 gene on chromosome Xq22.1.	Outdated component (foundation metadata concept)
A rare X-linked syndromic intellectual disability disorder with characteristics of profound intellectual disability, global developmental delay with absent speech, seizures, large joint contractures, abnormal position of thumbs and middle-age onset of cardiomegaly and atrioventricular valve abnormalities, resulting in subsequent congestive heart failure. Additional features include variable facial dysmorphism (notably large ears with over folded helix) and large testes. There is evidence the disease is caused by mutation in the CLIC2 gene on chromosome Xq28.	Outdated component (foundation metadata concept)
A rare X-linked syndromic intellectual disability which in symptomatic, female carriers has characteristics of a highly variable phenotype including facial dysmorphism (prominent forehead, hypertelorism, down-slanting palpebral fissures, epicanthic folds, thick lips with everted lower vermilion, thick nasal alae and septum), short hands with tapering fingers, short stature and skeletal findings (progressive kyphoscoliosis). Intellectual disability is mild to moderate, but intellect can also be normal. A high rate of psychiatric disorders has also been reported.	Outdated component (foundation metadata concept)
A rare X-linked syndromic intellectual disability with characteristics of developmental delay and intellectual disability, early hypotonia, constipation, feeding problems, imperforate anus, characteristic behavior (affable, eager to please) and dysmorphic craniofacial features (such as relative macrocephaly, prominent forehead with frontal hair upsweep, hypertelorism, downslanting palpebral fissures and open mouth). Additional manifestations are partial agenesis of the corpus callosum, sensorineural hearing loss, joint laxity, cardiac anomalies and abnormalities of the fingers and toes among others.

A rare X-linked syndromic intellectual disability with characteristics of global development delay, postnatal growth retardation leading to short stature, facial dysmorphism, short hands with tapering fingers and progressive skeletal abnormalities including kyphoscoliosis and pectus carinatum/excavatum. Severe clinical presentation was reported in the first male patients described. Following the wide application of molecular genetic testing, the phenotype is now recognised as very variable. Caused by pathogenic variations in the RPS6KA3 gene (Xp22.2-p22.1), which encodes ribosomal protein S6 kinase alpha-3, a growth-factor-regulated protein kinase. An X-linked dominant disorder, about two-thirds of cases occur de novo. Male offspring inheriting the mutation are affected and female carriers can be unaffected or show milder phenotypes.
