  129 2T A mutation had hand tremors and learning disabilities [ 6 ]; a boy with c.111_141ins had intellectual impairment [ 29 ]; microcephaly, developmental delay, and several minor dysmorphic features were noted in the sporadic patient with I87R mutation [molvis.org]

  Systemic features frequently include hand tremors and hypertonia. There is usually some degree of developmental delay ranging from fine motor difficulties to intellectual disabilities. [tsbvi.edu]

• Scanning Speech

  Other features include scanning speech, incoordination and attention tremor, and mental and motor retardation. Aetiology unknown. [whonamedit.com]

  Non-progressive cerebellar ataxia is associated with delayed developmental milestones and hypotonia (visible from the first year of life), gait and balance disorders with incoordination, intention tremor, and scanning speech. [orpha.net]

  People with this disorder may walk unsteadily and have difficulty positioning the feet and turning (cerebellar gait); they may also speak slowly and haltingly, with pauses between each syllable (scanning speech). [rarediseases.org]

• Mydriasis

  Gillespie syndrome reported as bilateral congenital mydriasis. Br J Ophthalmol. 1992;; 76 632-633 09 Richardson P, Schulenberg W E. Bilateral congenital mydriasis. Br J Ophthalmol. 1992;; 76 632-633 10 Wittig E O, Moreira C A, Friere-Maia N et al. [doi.org]

  Individuals with aniridia-cerebellar ataxia-mental deficiency may also have additional eye abnormalities, such as excessive widening (dilatation) of the pupils (mydriasis) and/or extreme sensitivity to light (photophobia). [rarediseases.org]

• Delayed Development of Motor Skills

  This abnormality can cause hypotonia and delayed development of motor skills such as walking. In addition, difficulty controlling the muscles of the mouth can lead to delayed speech development. [ghr.nlm.nih.gov]

Ectropion uveae is a common ocular finding whose presence in a neonate should prompt a workup for NF1. Other ocular findings associated with NF1 include Lisch nodules, optic nerve gliomas, eyelid neurofibromas, and glaucoma. [entokey.com]
