28 Possible Causes for Mental Retardation, Skeletal Dysplasia, Wide Space Between the First and Second Toe

  • Down Syndrome

    Dysplasia Society, Southeastern Regional Genetics Group Disclosure: Nothing to disclose.[emedicine.medscape.com] A wide space, often with a deep fissure between the first and second toes, is also common.[dx.doi.org] Abstract Although there is considerable variability, most individuals with Down syndrome have mental retardation and speech and language deficits, particularly in language[oadoi.org]

  • Seckel Syndrome

    Based on the clinical and radiological features showing evidence of skeletal dysplasia, the diagnosis was revised to Majewski osteodysplastic primordial dwarfism type II ([ncbi.nlm.nih.gov] 1st and 2nd toes Gap between first and second toe Increased space between first and second toes Sandal gap between first and second toes Wide space between 1st, 2nd toes[rarediseases.info.nih.gov] It is extremely rare and typically causes dwarfism, mental retardation, intrauterine growth retardation and microcephaly.[symptoma.com]

  • Atelosteogenesis Type 2

    Thanatophoric dysplasia and achondrogenesis account for 62% of all lethal skeletal dysplasias. Achondroplasia is the most common nonlethal skeletal dysplasia.[thehealthscience.com] 1st and 2nd toes Gap between first and second toe Increased space between first and second toes Sandal gap between first and second toes Wide space between 1st, 2nd toes[rarediseases.info.nih.gov] Retardation, Characteristic Facies, Short Stature, and Skeletal Anomalies KBGS 148050 Genetic Test Registry Kniest Dysplasia 156550 Genetic Test Registry Larsen Syndrome[ukgtn.nhs.uk]

  • Kenny-Caffey Syndrome Type 1

    Hereditary skeletal dysplasia resulting in proportionate dwarfism characterized by thickening of the inner corticalis and stenosis of the medullary cavities of the tubular[accessanesthesiology.mhmedical.com] Mental retardation of varying degree was found in all patients.

  • Greenberg Dysplasia

    Greenberg skeletal dysplasia is a very rare, autosomal recessive, in utero, lethal chondrodystrophy for which only eight index cases of diverse ethnic origin have been reported[ncbi.nlm.nih.gov] 1st and 2nd toes Gap between first and second toe Increased space between first and second toes Sandal gap between first and second toes Wide space between 1st, 2nd toes[rarediseases.info.nih.gov] Phenylketonuria (PKU) was then shown to be a treatable genetic disease in which early diagnosis and effective treatment prevented the disease (mental retardation) in PKU.[books.google.de]

  • Cutis Laxa

    In the neonatal period, brachydactyly and facial dysmorphism are two early distinctive signs, later followed by intellectual disability and hyperostotic skeletal dysplasia[ncbi.nlm.nih.gov] Other reported osteoarticular features are: a wide space between the first and second toes; talipes equinovarus; metatarsus adductus; genu recurvatum or genu valgum; flat[scielo.br] While the patients with GORAB mutations have severe osteopenia, the patients with PYCR1 mutations have severe mental retardation.[ncbi.nlm.nih.gov]
