What are the symptoms of Cockayne syndrome type II ?
What are the signs and symptoms of Cockayne syndrome type II? The Human Phenotype Ontology provides the following list of signs and symptoms for Cockayne syndrome type II. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormal auditory evoked potentials - Abnormal peripheral myelination - Abnormality of skin pigmentation - Abnormality of the hair - Abnormality of the pinna - Abnormality of visual evoked potentials - Anhidrosis - Arrhythmia - Ataxia - Atypical scarring of skin - Autosomal recessive inheritance - Basal ganglia calcification - Carious teeth - Cataract - Cerebellar calcifications - Cerebral atrophy - Cryptorchidism - Cutaneous photosensitivity - Decreased lacrimation - Decreased nerve conduction velocity - Delayed eruption of primary teeth - Dental malocclusion - Dermal atrophy - Dry hair - Dry skin - Hepatomegaly - Hypermetropia - Hypertension - Hypoplasia of teeth - Hypoplasia of the iris - Hypoplastic iliac wing - Hypoplastic pelvis - Increased cellular sensitivity to UV light - Intellectual disability - Intrauterine growth retardation - Ivory epiphyses of the phalanges of the hand - Kyphosis - Limitation of joint mobility - Loss of facial adipose tissue - Mandibular prognathia - Microcephaly - Microcornea - Micropenis - Microphthalmia - Muscle weakness - Normal pressure hydrocephalus - Nystagmus - Opacification of the corneal stroma - Optic atrophy - Osteoporosis - Patchy demyelination of subcortical white matter - Peripheral dysmyelination - Pigmentary retinopathy - Polyneuropathy - Postnatal growth retardation - Progeroid facial appearance - Proteinuria - Reduced subcutaneous adipose tissue - Renal insufficiency - Seizures - Sensorineural hearing impairment - Severe failure to thrive - Severe short stature - Slender nose - Small for gestational age - Sparse hair - Splenomegaly - Square pelvis bone - Strabismus - Subcortical white matter calcifications - Thickened calvaria - Tremor - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
