there are few reports about congenital indifference to pain or hereditary and sensory autonomic neuropathy (hsan). several investigations for pathophysiology of this syndrome have been performed and different classifications about it. in this report we present a case of hsan type ii with general absence of pain and self amputations and leprosy–like damage of extremities which was suspected to b...
how to cite this article: azadvari m, emami razavi sz, kazemi sh. hereditary sensory and autonomic neuropathy type iv in 9 year old boy: a case report. iran j child neurol. spring 2016; 10(2):83-85. abstract objective the hereditary sensory and autonomic neuropathy (hsan) is a rare group of neuropathies that affects the sensory and autonomic nervous system. the patients do not have the ability ...
hereditary sensory and autonomic neuropathies (hsan) are clinically and genetically a heterogeneous group of disorders. there are overlapping variants of hsan regarding clinical manifestations and pathologic findings. five types of hsan have been described by dyck (1993) and there are two other types which have been introduced recently. we report four siblings that seem to suffer from symptomat...
Dear Editor; We read with interest two recent papers on Congenital insensitivity to pain with anhidrosis, entitled " Congenital insensitivity to pain and anhydrosis (CIPA) syndrome; a report of 4 cases " by Daneshjou et al [1] and " Congenital insensitivity to pain with anhidrosis (HSAN type IV), extremely rare syndrome that can be easily missed by bone and joint surgeons: a case report " by Al...
There has been tremendous progress in the detection and diagnosis of hereditary neuropathies and while the genes responsible for these rare neuropathies have improved our understanding of the development of the sensory system, they remain clinical enigmas with rare occurrences and diverse presentations. In 1963, Swanson first described two brothers with congenital insensitivity to pain, anhidro...
ably affects development, as well as maintenance of neurons, because there is neuropathological and clinical progression. Inherited autonomic neuropathies are a rare group of disorders associated with sensory dysfunction. As a group they are termed the "hereditary sensory and autonomic neuropathies" (HSAN). Classification of the various autonomic and sensory disorders is ongoing. Phenotypic exp...
Charcot-Marie-Tooth disease (CMT) and related neuropathies are a genetically highly heterogeneous group of neurodegenerative disorders. CMT affects both the sensory and motor nerves, distal Hereditary Motor Neuropathies (dHMN) are phenotypically similar disorders involving only motor nerves, while Hereditary Sensory and Autonomic Neuropathies (HSAN) are rare distinct disorders affecting sensory...
The genetic neuropathies are a clinically and genetically heterogeneous group of diseases of which the most common types are Charcot-Marie-Tooth disease (CMT), the hereditary sensory and autonomic neuropathies and the distal hereditary motor neuropathies. More than 30 causative genes have been described, making an accurate genetic diagnosis increasingly possible. Although no specific therapies ...
Many neurodegenerative disorders present with sensory loss. In the group of hereditary sensory and autonomic neuropathies loss of nociception is one of the disease hallmarks. To determine underlying factors of sensory neurodegeneration we performed whole-exome sequencing in affected individuals with the disorder. In a family with sensory neuropathy with loss of pain perception and destruction o...
