| Intellectual disability-alacrima-achalasia syndrome is a rare, genetic intellectual disability syndrome characterized by delayed motor and cognitive development, absence or severe delay in speech development, intellectual disability, and alacrima. Achalasia/dysphagia and mild autonomic dysfunction (i.e. anisocoria) have also been reported in some patients. The phenotype is similar to the one observed in autosomal recessive Triple A syndrome but differs by the presence of intellectual disability in all affected individuals. |

| A rare, combined T and B cell immunodeficiency characterized by childhood onset of recurrent bacterial and varicella zoster virus infections. Eczema and recurrent molluscum have also been reported. Laboratory studies reveal profound and persistent lymphopenia, hypogammaglobulinemia, poor immune response to vaccine antigens, and fluctuating neutropenia. |

| A rare genetic cardiac malformation characterized by progressive myxomatous degeneration predominantly of the mitral valve (but not uncommonly with multivalvular involvement), presenting as valve thickening and dysfunction with variable stenosis, prolapse, and/or regurgitation, and potentially resulting in lethal heart failure. Hyperextensible skin and joint hypermobility have been reported in some patients. Hemizygous males display a more severe phenotype than heterozygous females. |

| Macrocephaly-intellectual disability-left ventricular non compaction syndrome is a rare, genetic, syndromic intellectual disability characterized by motor and cognitive developmental delay with language impairment, macrocephaly, hypotonia, dysmorphic facial features (including long face, slanting palpebral fissures and prominent, flattened nose) and left ventricular noncompaction cardiomyopathy. Patients also present skeletal abnormalities (e.g. scoliosis, finger clinodactyly, pes planus), slender build and shy behavior. Strabismus and various neurological signs (including ataxia, tremor and hyperreflexia) may be associated, as well as epilepsy, autism and MRI findings showing a small cerebellum and abnormalities of the corpus callosum. A phenotypic variant with no cardiac involvement has been reported. |

| X-linked microcephaly-growth retardation-prognathism-cryptorchidism syndrome is a rare syndromic intellectual disability characterized by hypotonia, microcephaly, severe developmental delay, seizures, intellectual disability, growth retardation, cardiac septal defects, cryptorchidism, hypospadias, and dysmorphic features - prominent ears, prognathism, thin upper lip, dental crowding. |

| A rare genetic multiple congenital anomalies/dysmorphic syndrome characterized by global developmental delay, intellectual disability, growth retardation, hypotonia, cerebellar symptoms such as ataxia, spondyloepiphyseal dysplasia, and dysmorphic craniofacial features (including microcephaly, dolichocephaly, prominent ears, epicanthus, broad nasal bridge, long and flat philtrum, or small mouth). Additional reported manifestations are epilepsy, retinitis pigmentosa, and urogenital abnormalities, among others. Brain imaging may show cerebellar hypoplasia. |

| A rare X-linked syndromic intellectual disability characterized by 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. |

Various ophthalmic, cutaneous, musculoskeletal, gastrointestinal, and cardiovascular anomalies have also been described. |

| X-linked intellectual disability-short stature-overweight syndrome is a multiple congenital anomalies syndrome characterised by borderline to severe intellectual disability, speech delay, short stature, elevated body mass index, a pattern of truncal obesity (reported in older males), and variable neurologic features (e.g. hypotonia, tremors, gait disturbances, behavioural problems, and seizure disorders). Less common manifestations include microcephaly, microorchidism and/or microphallus. Dysmorphic features have been reported in some patients but no consistent pattern has been noted. |

| A rare form of spinal muscular atrophy characterized by the neonatal onset of severe hypotonia, areflexia, profound weakness, multiple congenital contractures, facial dysmorphic features (myopathic face with open, tent-shaped mouth), cryptorchidism, and mild skeletal abnormalities (i.e. kyphosis, scoliosis), that is often preceded by polyhydramnios and reduced fetal movements in utero and followed by bone fractures shortly after birth. Muscle weakness is progressive and chest muscle involvement eventually leads to ventilatory insufficiency and respiratory failure. |
