12 Possible Causes for All Reported Mutations Have Occurred De Novo, Failure to Thrive

  • Lissencephaly

    Symptoms of the disorder may include unusual facial appearance, difficulty swallowing, failure to thrive, muscle spasms, seizures, and severe psychomotor retardation.[] So far, all mutations in TUBA1A have occurred de novo, resulting in isolated cases.[] CONCLUSIONS: Mutations in TUBA1A have been described in patients with lissencephaly and pachygyria. We report a mutation in TUBA1A as a cause of polymicrogyria.[]

  • Hypopituitarism

    , fatigue Children/infants – failure to thrive Posterior pituitary (hypothalamic) Central diabetes insipidus Adults – polydipsia, polyuria, nocturia Children – vomiting, diarrhea[] All of these mutations occurred de novo and included five nonsense, four frameshift, one deletion and two missense mutations.[] […] pubertal development Infants – cryptorchidism, microphallus GH Adults – fatigue, decreased muscle mass and strength, reduced bone marrow density Children – short stature, failure[]

  • Dystrophic Epidermolysis Bullosa

    […] to thrive.[] All cases with localised DDEB have not necessarily been documented or registered in DEB databases and therefore those mutation reports are limited.[] Failure to thrive, cheilitis, hypohidrosis, and pruritus are other potential complications.[]

  • Geleophysic Dysplasia

    Geleophysic Dysplasia is characterised by extremely short stature, small hands and feet, failure to thrive and accompanying physical disabilities including progressive heart[] All reported mutations have occurred as new (sporadic or de novo ) mutations, which means that in these cases the gene mutation has occurred at the time of the formation of[]

  • Optic Atrophy

    Both affected sisters presented with a similar cluster of neurodevelopmental deficits marked by failure to thrive, generalised neuromuscular weakness and optic atrophy.[] Although almost all benign mutations were inherited, the majority of severe mutations occurred de novo.[] Of interest, de novo SCN2A mutations have also been reported in five patients without seizures but with ID (n 3) and/or autism (n 3).[]

  • Cerebro-Costo-Mandibular Syndrome

    Feeding problems and its outcome failure to thrive is an additional problem in these babies.[] reported mutations have occurred de novo; Facial dysmorphic features are variable MOLECULAR BASIS: Caused by mutation in the K(lysine) acetyltransferase 6A gene (KAT6A, 601408.0001[] […] to thrive and conductive hearing loss (seen in about 10 % of cases). [3], [9] The developmental anomalies in our case with the estimated percentage of those described in[]

  • Anophthalmia - Microphthalmia Syndrome

    […] to thrive; ID intellectual disability; SNHL sensorineural hearing loss Footnotes: 1.[] All remaining reported cases of SOX2 mutations and deletions have occurred de novo.[] Developmental Disorders Associated with Failure to Thrive Eurekah Bioscience Collection Cranial Neural Crest and Development of the Head Skeleton Reviews Bookshelf vision[]

  • Helsmoortel-van der Aa Syndrome

    Transient neonatal seizures, nystagmus, strabismus and failure to thrive are also seen in most cases.[] […] to thrive, hearing loss Infantile hepatocerebral mtDNA depletion Frequent vomiting MR [23] [23] [28] [14] [15] [15] [15] [13,29] [13,29] [13,29] [13,30] [16] [16] [16] [13[] […] disorders Short Chain Acyl CoA Dehydrogenase deficiency (SCAD) Short Chain Hydroxy Acyl CoA Dehydrogenase deficiency (SCHAD) SCAD deficiency presents in the neonatal period with failure-to-thrive[]

  • Cutaneous Mastocytosis - Short Stature - Conductive Hearing Loss - Microtia

    […] to thrive 60 33 hallmark (90%) Very frequent (99-80%) HP:0001508 5 microtia 60 33 hallmark (90%) Very frequent (99-80%) HP:0008551 6 microcephaly 60 33 hallmark (90%) Very[] reported mutations have occurred de novo MOLECULAR BASIS: Caused by mutation in the nonselective sodium leak channel gene (NALCN, 611549.0004) Description The large number[] […] to thrive 59 32 hallmark (90%) Very frequent (99-80%) HP:0001508 6 respiratory insufficiency 59 32 occasional (7.5%) Occasional (29-5%) HP:0002093 7 hypotension 59 32 occasional[]

  • Anophthalmia or Microphthalmia - Esophageal Atresia Syndrome

    […] to thrive / difficulties for feeding in infancy / growth delay - Holoprosencephaly / arhinencephaly / unique lateral ventricle - Hydrocephaly - Hypospadias / epispadias [] All remaining reported cases of SOX2 mutations and deletions have occurred de novo.[] A failure to thrive (length and weight, head circumference on third centile) due to gastroesophageal reflux was documented.[]
