Introduction
SPG11 mutation-related autosomal recessive hereditary spastic paraplegia with thin corpus callosum (HSP-TCC) is a common cause of early-onset mental retardation followed by progressive spastic paraplegias.
SPG11 mutation-related HSP-TCC is a common cause of early-onset mental retardation followed by progressive spastic paraplegias. This autosomal recessive condition is characterized by neurological manifestations such as thin corpus callosum‚ muscle stiffness‚ and cognitive decline. Understanding the genetic basis and clinical presentation of HSP-TCC is crucial for accurate diagnosis and management strategies.
Background Information
SPG11 mutation-related autosomal recessive hereditary spastic paraplegia with thin corpus callosum (HSP-TCC) is a common cause in complicated forms of HSP‚ typically presenting mental retardation and spastic paraplegias in childhood.
Understanding the genetic basis of HSP-TCC
SPG11 mutation-related HSP-TCC is an autosomal recessive disorder involving a genetic abnormality that leads to the deterioration of long nerves in the spine‚ causing progressive spastic paraplegias and mental retardation. The faulty SPG11 gene plays a critical role in the pathophysiology of this condition‚ impacting nerve function and cognitive decline.
Clinical presentation of SPG11 mutation-related HSP-TCC
SPG11 mutation-related HSP-TCC commonly presents with early-onset mental retardation followed by progressive spastic paraplegias. Neurological manifestations include thin corpus callosum‚ muscle stiffness‚ and cognitive decline‚ with some cases showing late-onset symptoms and sporadic presentation.
Clinical Features
Individuals with thin corpus callosum and mental retardation commonly present a combination of symptoms‚ including spastic paraplegias‚ muscle stiffness‚ cognitive decline‚ and neurological manifestations.
Characteristics of individuals with thin corpus callosum and mental retardation
Individuals with thin corpus callosum and mental retardation may exhibit a variety of symptoms‚ including spastic paraplegias‚ muscle stiffness‚ cognitive decline‚ and neurological manifestations. These individuals often present with early-onset mental retardation‚ followed by progressive spastic paraplegias‚ indicating the complex nature of the condition and the impact on both cognitive and motor functions.
Neurological manifestations in affected families
Families affected by SPG11 mutation-related HSP-TCC show a range of neurological manifestations‚ including thin corpus callosum‚ mental retardation‚ and spastic paraplegias. While some individuals exhibit these symptoms from early childhood‚ others may develop late-onset signs with varying family histories‚ highlighting the complex nature and diverse presentations of the condition.
Diagnosis and Differential Diagnosis
The diagnostic criteria for autosomal recessive HSP with thin corpus callosum include autosomal recessive inheritance‚ slowly progressive spastic paraparesis‚ mental impairment‚ and thinning of the corpus callosum. Differential diagnosis explores various rare neuro-metabolic diseases that present with progressive spastic paraparesis‚ including cerebro-tendinous xanthomatosis‚ adrenomyeloneuropathy‚ and hypovitaminosis.
