Type II; Acroosteolysis, Giaccai Type; Acroosteolysis, Neurogenic; Congenital Sensory Neuropathy; HSAN II ; Hereditary Sensory Radicular Neuropathy, Autosomal Recessive; Hereditary Sensory and Autonomic Neuropathy, Type II (HSAN Type II); Morvan Disease; Neuropathy, Progressive Sensory, of Children; Radicular Neuropathy, Sensory, Recessive; Sensory Radicular Neuropathy, Recessive; The hereditary sensory neuropathies (HSN) include 4-6 similar but distinct inherited degenerative disorders of the nervous system (neurodegenerative) that frequently progress to loss of feeling, especially in the hands and feet; Some types of HSN are related to or identical with some forms of Charcot-Marie-Tooth disorder, and others are related to or identical with familial dysautonomia (Riley-Day syndrome); The classification of the HSNs is complicated, and the experts do not always agree on it; Hereditary sensory neuropathy type II (HSN2) is a rare genetic disorder that usually begins in childhood by affecting the nerves that serve the lower arms and hands and the lower legs and feet (the peripheral nerves); Symptoms start with inflamed fingers or toes especially around the nails; Infection is common and worsens as ulcers (open sores) form on the fingers and on the soles of the feet; The loss of sensation in both hands and feet often leads to neglect of the wounds; This can become serious, even leading to amputation in extreme cases, so it is important to care for any such wounds; The disorder affects many of the body’s systems, is characterized by early onset (infancy or early childhood) and is transmitted genetically as an autosomal recessive trait-----[NORD 2005]---------
