Tsukuhara syndrome, also known as Radioulnar synostosis-microcephaly-scoliosis syndrome is an infrequently occurring genetic skeletal dysplasia which is characterized by a combination of radioulnar synostosis, microcephaly, scoliosis, short height, and intellectual disabilities. Only 13 cases worldwide have been described in medical literature.
Goldberg–Shprintzen is a very rare connective tissue condition associated with mutations in KIAA1279 gene which encodes KIF-binding protein (KBP), a protein that may interact with microtubules and actin filaments. KBP may play a key role in cytoskeleton formation and neurite growth.
Myhre syndrome is a rare genetic disorder inherited in an autosomal dominant fashion. It is caused by mutation in SMAD4 gene.
Gordon syndrome, or distal arthrogryposis type 3, is a rare genetic disorder characterized by cleft palate and congenital contractures of the hands and feet.
Lowry-Wood syndrome, also simply known as LWS, is a very rare genetic disorder which is characterized by dysplasia of the epiphysis, low height/short stature, microcephaly, developmental delay, intellectual disabilities, and congenital nystagmus. Less common features include coxa vara and retinitis pigmentosa. Only 10 cases of this disorder have been described in medical literature. This disorder is associated with mutations in the RNU4ATAC gene, on chromosome 2q14.2
Al Gazali Sabrinathan Nair syndrome, also known as Al Gazali-Nair syndrome is a very rare multi-systemic genetic disorder which is characterized by developmental delay, facial dysmorphy, and skeletal and ocular abnormalities. This disorder was first described in two siblings that came from consanguineous parents. No new cases have been described since 1994.
Saito-Kuba-Tsuruta syndrome, also known as Fibulo-ulnar hypoplasia-renal anomalies syndrome, is a very rare genetic disorder which is characterized by fibulo-ulnar dysplasia associated with renal abnormalities. It is associated with neo-natal respiratory failure soon after birth.
Anophthalmia megalocornea cardiopathy skeletal anomalies syndrome is an extremely rare multi-systemic genetic disorder which is characterized by congenital ocular, muscular, and heart abnormalities. It was first described in the children of a consanguineous couple,and it is thought to be autosomal recessive disorder with variable expressity.No new cases have been described in medical literature since 1992.
Multiple congenital anomalies-hypotonia-seizures syndrome is a rare multi-systemic genetic disorder which is characterized by developmental delay, seizures, hypotonia and heart, urinary, and gastrointestinal abnormalities.
Brachydactyly-long thumb syndrome is a very rare genetic disorder which is characterized by symmetric brachydactyly of the fingers accompanied by an abnormally long thumb, hypomobility of the shoulder and metacarpo-phalangeal joints, and heart conduction defects. Small feet and hands, small shoulders accompanied with short clavicles, clinodactyly, pectus excavatum, mild limb shortening, cardiomegaly, and pulmonic stenosis murmur have also been reported. It was first discovered when D W Hollister et al. described 4 affected members belonging to a 3-generation family. No new cases have been reported since 1981. This disorder is inherited in an autosomal dominant manner.
Aortic arch anomaly - peculiar facies - intellectual disability is a rare, genetic, congenital developmental anomaly which is characterized by heart abnormalities, cranio-facial dysmorphia, and intellectual disabilities. No new cases have been reported since 1968.
Gustavson syndrome, also known as Severe X-linked intellectual disability, Gustavson type, is a rare genetic disorder which is characterized by severe intellectual disabilities, microcephaly, developmental delay, optic atrophy-induced severe vision impairment/loss, severe hearing loss, spasticity, epilepsy, hypomobility of major joints, facial dysmorphisms, and premature death. This disorder was first discovered in 1993, by Gustavson et al., when they described 7 male children from a 2-generation family, these children had the symptoms mentioned above, they came to the conclusion that this case was part of a novel X-linked recessive syndrome. No new cases have been reported since then (1993).
Cryptorchidism-arachnodactyly-intellectual disability syndrome is a rare multi-systemic genetic disorder of unknown prevalence which is characterized by psycho-motor developmental delay, severe intellectual disabilities, severe muscle hypoplasia, absence of subcutaneous fat, generalized contractures, dolichocephaly, esotropia, asymmetric ears, and high palate, kyphoscoliosis, unilateral hypoplasia of the bronchial system, recurrent respiratory tract infections, atelectasis, arachnodactyly, cryptorchidism, hypospadias, and testicular agenesis. No new cases have been reported since 1970.
Thickened earlobes-conductive deafness syndrome, also known as Escher-Hirt syndrome, or Schweitzer Kemink Graham syndrome, is a rare genetic disorder which is characterized by ear and jaw abnormalities associated with progressive hearing loss. Two families worldwide have been described with the disorder.
Absent tibia-polydactyly-arachnoid cyst syndrome, also known as Holmes-Collins syndrome, is a very rare multi-systemic hereditary disorder which is characterized by facial dysmorphisms, pre/post-axial polydactyly, toe syndactyly, missing/underdeveloped tibia bone, and the presence of a retrocerebellar arachnoid cyst. Additional findings include clubbed feet, cleft lip, diaphragm agenesis, and radial and ulnar anomalies.
Blepharophimosis intellectual disability syndromes are a group of rare genetic disorders which are characterized by blepharophimosis, ptosis and intellectual disabilities. These disorders usually follow one of the following inheritance patterns: autosomal recessive, autosomal dominant, x-linked recessive, and mitochondrial.

Pierre Robin sequence-faciodigital anomaly syndrome, also known as Chitayat Meunier Hodgkinson syndrome, is a very rare genetic disorder which is characterized by the signs typical of Pierre Robin sequence along with facial dysmorphisms and digital anomalies. Intellect is not affected. It is thought to be inherited in an X-linked recessive manner.
Mandibulofacial dysostosis with microcephaly syndrome, also known as growth delay-intellectual disability-mandibulofacial dysostosis-microcephaly-cleft palate syndrome, mandibulofacial dysostosis, guion-almeida type, or simply as MFDM syndrome is a rare genetic disorder which is characterized by developmental delays, intellectual disabilities, and craniofacial dysmorphisms.
