Summaries for Poretti-Boltshauser Syndrome

OMIM : ⁵⁷ Poretti-Boltshauser syndrome is an autosomal recessive disorder characterized by cerebellar dysplasia, cerebellar vermis hypoplasia, cerebellar cysts in most patients, high myopia, variable retinal dystrophy, and eye movement abnormalities. Affected individuals have delayed motor development and often have speech delay. Cognitive function can range from normal to intellectually disabled (summary by Aldinger et al., 2014). (615960)

MalaCards based summary : Poretti-Boltshauser Syndrome, also known as ptbhs, is related to retinitis. An important gene associated with Poretti-Boltshauser Syndrome is LAMA1 (Laminin Subunit Alpha 1). Affiliated tissues include eye and pons, and related phenotypes are nystagmus and delayed speech and language development

UniProtKB/Swiss-Prot : ⁷⁵ Poretti-Boltshauser syndrome: An autosomal recessive disorder characterized by cerebellar dysplasia, cerebellar vermis atrophy, cerebellar cysts in most patients, high myopia, variable retinal dystrophy, and eye movement abnormalities including strabismus, ocular apraxia, nystagmus. Affected individuals have ataxia, delayed motor development, language impairment, and intellectual disability with variable severity.
