Congenital insensitivity to pain with anhidrosis: case report* Nikolas Kouvelas, DDS, Dip Pedo Catherine Terzoglou, DDS Abstract Congenital insensitivity to pain with anhidrosis is a rare disorder. This article uses CIP broadly to describe features common to all H… 2,3 The failure of internal fixation, infection and wound breakdown are … Rivka Carmi is an Israeli pediatrician and geneticist. This defect primarily affects skeletal muscle fibres and causes muscular weakness and/or hypotonia. This enzyme catalyzes the biodegradation of fatty acid derivatives known as gangliosides. It is also sometimes referred to as hereditary sensory and autonomic neuropathy type IV (HSAN4). We use cookies to help provide and enhance our service and tailor content and ads. CIPA is the fourth type of hereditary sensory and autonomic neuropathy (HSAN), and is also known as HSAN IV. This is a retrospective study including 7 patients diagnosed with CIPA presenting to Jordan University Hospital neurology clinic between 2001 and 2017. Congenital insensitivity to pain with anhidrosis (CIPA) also known as hereditary … Congenital insensitivity to pain with anhidrosis, also known as hereditary sensory and autonomic neuropathy type IV, is an autosomal recessive disorder characterized by the congenital lack of pain sensation, inability to sweat, episodes of recurrent hyperpyrexia, … The … While their peers are learning to eat hard foods, they must eat soft foods and are thus often left … Poor weight gain, microcephaly and global developmental delay were present in most cases. This rare autosomal recessive disorder is also known as congenital sensory neuropathy with anhidrosis or hereditary sensory and autonomic neuropathy type IV or familial dysautonomia type II. The skin over the medial aspect of the ankle is darkened with a draining wound secondary to superimposed. Because feeling physical pain is vital for survival, CIP is an extremely dangerous condition. Characterized by a congenital insensitivity to pain, anhidrosis (absence of sweating), absence of reaction to noxious stimuli, self-mutilating behavior, and mental retardation. HMSN are characterised by atypical neural development and degradation of neural tissue. A new mutation variant in c.2170 G > A is reported with probably a milder phenotype. © 2019 Elsevier B.V.

Skin biopsies show a lack of innervation of the eccrine glands [2] and nerve biopsies show a lack of small myelinated and unmyelinated fibers. Cognitive disorders are commonly coincident. PR domain zinc finger protein 12 is a protein that in humans is encoded by the PRDM12 gene. SCN manifests in infancy with life-threatening bacterial infections. The sense of touch and vibration is not affected. Familial dysautonomia (FD) is a rare, progressive, recessive genetic disorder of the autonomic nervous system seen primarily in people of Eastern European Jewish descent that affects the development and survival of sensory, sympathetic and some parasympathetic neurons in the autonomic and sensory nervous system.

Congenital insensitivity to pain with anhidrosis is a rare autosomal recessive disorder caused by pathogenic variants in the gene NTRK1. The disorder is autosomal recessive. The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles (myotonia) and rigidity. Congenital insensitivity to pain with anhidrosis (CIPA; MIM 256800) is a rare autosomal recessive disorder characterized by recurrent episodes of unexplained fever, anhidrosis (inability to sweat), absence of reaction to noxious stimuli, self-mutilating behavior and mental retardation (31, 32). Three clinical findings define the syndrome: insensitivity to pain, impossibility to sweat, and mental retardation. Symptoms include delayed relaxation of the muscles after voluntary contraction (myotonia), and may also include stiffness, hypertrophy (enlargement), transient weakness in some forms of the disorder, severe masseter spasm, and cramping. The congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive disease caused by mutations in NTRK1 gene (neurotrophic tyrosine kinase receptor 1) located in chromosome 1q21-22, encoding the tyrosinase domain receptor high affinity nerve growth factor. Congenital insensitivity to pain with anhidrosis or CIPA is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. A number sign (#) is used with this entry because congenital insensitivity to pain with anhidrosis (CIPA) is caused by homozygous or compound heterozygous mutation in the NTRK1 gene (191315) on chromosome 1q23. Clinical Features. This cohort reveals a severe HSAN IV phenotype in Jordanian patients. Congenital insensitivity to pain and anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV is an extremely rare syndrome. The frameshift (c.1860_1861insT; p.Pro621fs) mutation was common in our series. Congenital insensitivity to pain with anhidrosis (CIPA) is a rare disease classified as hereditary sensory and auto-nomic neuropathy (HSAN) type IV [1, 2] according to Dyck et al.

Complications can include muscle breakdown and high blood potassium. Myelin- ated fibres were decreased to 3,219 per sq.mm compared with hereditary sensory neuropathy. Since congenital insensitivity to pain with anhidrosis syndrome is a rare disease, a child with this syndrome is presented here to draw attention to early diagnosis. [ citation needed ], It is caused by a mutation in NTRK1, a gene encoding the neurotrophic tyrosine kinase receptor. Hereditary inclusion body myopathies comprise both autosomal recessive and autosomal dominant muscle disorders that have a variable expression (phenotype) in individuals, but all share similar structural features in the muscles. Methods. Attention to injuries to prevent infection and worsening is necessary. At first glance, individuals with congenital insensitivity to pain with anhidrosis (CIPA) may seem quite lucky. Mutation analysis revealed three variants in NTRK1 gene. [2] [6], Diagnosis is made based on clinical criteria and can be confirmed with genetic testing. [4] NTRK1 is a receptor for nerve growth factor (NGF). Fingers/toes ulcerations were present in 6/7 (86.0 %), hip joint dislocation in 3/7 (43.0 %), chronic arthritis and joint swelling in 6/7 (86.0 %), corneal ulcers in 4/7 (57.1 %) and kidney amyloidosis in 1/7 (13.0 %) of all patients. The prevalence is estimated at 1 in 50,000 live births. While it has been observed in different ethnicities, the incidence appears to be higher in the Japanese population and in Sephardic Jews from Morocco. [2] Joint and bone problems are common due to repeated injuries, and wounds heal poorly. Congenital insensitivity to pain with anhidrosis (CIPA) is a rare inherited disorder of the nervous system which prevents the sensation of pain, heat, and cold. Congenital insensitivity to pain with anhidrosis (CIPA) is a genetic condition with two characteristic features – the inability to feel pain and temperature and a significant lack of sweating. In these disorders, a patient experiences progressive muscle atrophy and sensory neuropathy of the extremities. As a whole, congenital myopathies can be broadly classified as follows: Central core disease (CCD), also known as central core myopathy, is an autosomal dominantly inherited muscle disorder present from birth that negatively affects the skeletal muscles. Quantitative studies and electron microscopy of the cutaneous branch of the radial nerve revealed almost complete absence of small myelinated and unmyelinated fibers and a disproportionate number of nerve fibers with a diameter of 6–10 μm. https://doi.org/10.1016/j.clineuro.2019.105636. Infants may present with seizures related to hyperthermia. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. [1], There is no treatment for CIPA. Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive disorder of the nervous system which prevents the feeling of pain or temperature, and prevents a person from sweating. Hereditary motor and sensory neuropathies (HMSN) is a name sometimes given to a group of different neuropathies which are all characterized by their impact upon both afferent and efferent neural communication. All patients had tongue ulcerations. Consanguinity was present in all families. [1], who categorized congenital hyposensitiv-ity to pain into five different types of HSANs. [2]. A genetic disorder is a health problem caused by one or more abnormalities in the genome. [1] It is part of a group known as hereditary sensory and autonomic neuropathies. Congenital insensitivity to pain with anhidrosis (CIPA) has two characteristic features: the inability to feel pain and temperature, and decreased or absent sweating (anhidrosis). Congenital insensitivity to pain with anhidrosis (CIPA, MIM 256800), also known as hereditary sensory and autonomic neuropathy type IV (HSAN-IV) is a rare autosomal recessive disorder that was first described about 50 years ago [ 1 ].
