Summaries for Spastic Paraplegia 51, Autosomal Recessive

UniProtKB/Swiss-Prot : 73 Spastic paraplegia 51, autosomal recessive: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. SPG51 is a non-progressive disorder of movement and/or posture resulting from defects in the developing central nervous system. Affected individuals manifest motor and posture impairments often associated with epilepsy and disturbances of cognition, behavior, sensation, and communication.

MalaCards based summary : Spastic Paraplegia 51, Autosomal Recessive, also known as spg51, is related to hereditary spastic paraplegia 51 and ap-4-associated hereditary spastic paraplegia, and has symptoms including seizures An important gene associated with Spastic Paraplegia 51, Autosomal Recessive is AP4E1 (Adaptor Related Protein Complex 4 Subunit Epsilon 1), and among its related pathways/superpathways are Vesicle-mediated transport and Clathrin derived vesicle budding. Affiliated tissues include eye, bone and skin, and related phenotypes are microcephaly and intellectual disability, severe

OMIM : 56 Spastic paraplegia-51 is an autosomal recessive neurodevelopmental disorder characterized by neonatal hypotonia that progresses to hypertonia and spasticity and severe mental retardation with poor or absent speech development (summary by Moreno-De-Luca et al., 2011). (613744)
