UniProtKB/Swiss-Prot : ⁷³ Spastic paraplegia 49, autosomal recessive: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. Complicated forms are recognized by additional variable features including spastic quadriparesis, seizures, dementia, amyotrophy, extrapyramidal disturbance, cerebral or cerebellar atrophy, optic atrophy, and peripheral neuropathy, as well as by extra neurological manifestations. SPG49 is characterized by delayed psychomotor development, mental retardation, and onset of spastic paraplegia in the first decade. Affected individuals also have dysmorphic features, thin corpus callosum on brain imaging, and episodes of central apnea, which may be fatal.

MalaCards based summary : Spastic Paraplegia 49, Autosomal Recessive, also known as spg49, is related to nescav syndrome and neuroaxonal dystrophy, and has symptoms including gait ataxia An important gene associated with Spastic Paraplegia 49, Autosomal Recessive is TECPR2 (Tectonin Beta-Propeller Repeat Containing 2). Related phenotypes are recurrent respiratory infections and intellectual disability

Disease Ontology : ¹² A hereditary spastic paraplegia that has material basis in mutation in the TECPR2 gene on chromosome 14q32.

GARD : ²⁰ The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 320385DefinitionHereditary sensory and autonomic neuropathy due to TECPR2 mutation is a rare genetic peripheral neuropathy characterized by early hypotonia evolving to spastic paraparesis, areflexia, decreased pain and temperature sensitivity, autonomic neuropathy, gastroesophageal reflux disease, recurrent pneumonia and respiratory problems. Patients also have intellectual disability and dysmorphic features, including mild brachycephalic microcephaly, short broad neck, low anterior hairline and coarse face.Visit the Orphanet disease page for more resources.

OMIM® : ⁵⁷ SPG49 is an autosomal recessive complicated form of spastic paraplegia, a neurodegenerative disorder of the corticospinal tracts. It is characterized by delayed psychomotor development, mental retardation, and onset of spastic paraplegia in the first decade. Affected individuals also have dysmorphic features, thin corpus callosum on brain imaging, and episodes of central apnea, which may be fatal (summary by Oz-Levi et al., 2012).
