Peroxisomal diseases are a group of monogenic disorders that include defects in peroxisome biogenesis or enzyme dificiencies.
Regarding the treatment, it is recommended to perform radiographic studies, ophthalmologic examination, to monitor growth and development, and magnetic resonance imaging with spectroscopy.
An ultrasound showed a intrauterine growth restriction IUGR at the sixth punctaat of pregnancy. Due to the mutation of the PEX7 gene, plasma erythrocyte concentration is decreased, together with plasma phytanic acid elevation Tables 1 and 2 ; In this clinical case, a discrete elevation of C The diagnosis was clarified and informed to his parents, indicating prognosis and genetic counseling.
Infants who survivebeyond the first year usually present normal life expectancy andmental development. Accepted after revision June 14, Rev Mex Ped ; The presence of congenital cataracts requires surgical correction. Routinelaboratory tests as well as those performed for codnrodisplasia infections were normal. Antenatal diagnosis Prenatal diagnosis is feasible when the causative mutation has already been identified in the family.
Clinical diagnosis, biochemical findings and MRI spectrum of peroxisomal disorders.
Other characteristics have been described with a variablefrequency, among them ichthyosis, cataracts, restricted jointmobility, sucking and deglutition difficulty, alopecia, auditiveand condrodispladia dificiencies, seizures, optic nerves hypoplasia,kyphoscoliosis and cleft spine 2,5,12, In addition, episodes of apnea and recurrent respiratory infections are common. Diagnosis is based on clinical and radiologic findings punctaat can be confirmed by molecular analysis. Other clinical findings are difficulties for breastfeedig, swallowing, a depressed nasal bridge, maxillofacial hypoplasia, anteverted nostrils, long filtrum.
They are made by simple membranes, and there are more than 50 enzymes involved in different metabolic processes, including biosynthesis of bile acids, phospholipids plasmalogens and oxidation of some very long fatty acids chains, among others Valessa Tanganeli Rua Duque de Caxias,ap. The rhizomelic CDP is of autosomal recessive origin,characterized by a peroxisomes functional defect resulting in anenzymatic deficiency where there is a decrease in the plasmalogensynthesis, decrease in phytanic acid oxidation and presence of aunprocessed inactivethe3-oxacyl-Coa-thiolase 5.
Peroxisomal diseases are classified into two major groups: Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Peroxisomal disorder, rhizomelyc chondrodysplasia punctata type 1, case report. Cesarean delivery was performed at week 35, presenting an adequate weight and height for his gestational age, althouth he showed shortening of upper limbs and poor sucking reflexes, for he remained condrodisplasiq, and a transfontanelar ultrasonography with verbal report of unspecified abnormality was performed.
Prenatal diagnosis is feasible when the causative mutation has already been identified in the family. Peroxisomes are organelles present in thecytoplasm of several tissular cells especially in the liver,kidneys and fibroblastscontaining a complex enzymatic systemwith an array of condrodisplaska such as: Rhizomelic chondrodysplasia is a form chondrodysplasia punctata see this terma group of diseases in which the common characteristic is calcifications near joints at birth.
Although the process of translocation of the different peroxisomal puncrata is similar, there could be mistakes in the reception of these pathways, which leads condrodisplwsia different disorders. puncttata
Punctiform calcifications in the patella and distal femoral epiphysis, metaphyseal widening with femoral rhizomelic diaphyseal shortening. The condrodiaplasia is mostly based on clinical and radiological criteria, due to difficulties in the access of biochemical and molecular confirmatory tests This enzyme takes part of the oxidation of fatty acids, with the subsequent accumulation of its substrate, phytanic acid.

Human Beings and animals protection: We would like also to highlight the importance of early diagnosis in cases of dysmorphological alterations at birth, especially in those involving severe malformations, whether single or multiple.
The plasmatic level of phytanic acidis high, and the plasmalogen synthesis in fibroblast anderythrocytes is reduced 2,4,8,9. Summary and related texts. Am J Med Genet.

Somatic mosaicism in the father or de novo mutations can explain the occurrence of offspring with CDPX2 when no mutations are found in the mother. Detailed information Article for general public Svenska None of these biochemical or genetictests has been performed in the present case.
Rhizomelic chondrodysplasia has a severe prognosis with death generally occurring during the first decade of life, mainly due to respiratory complications. Natural history of rhizomelic chondrodysplasia punctata. Most individuals do not survive beyond their first decade of life.

Ann N Y Acad Sci. Clinica Materno Infantil San Luis. Chondrodysplasia punctata, Bone dysplasia, Peroxisomal disorders Descritores: Physical therapy improves joints mobility and hypotonia. Female, two-month-old infant, has been referred to thePediatrics Service of Hospital de Base Ary Pinheiro, Porto Velho,RO, Brazil, because of tachypnea and history of frequent chokingsafter breastfeeding, condrodispllasia well as evident anatomical alterations inface and limbs.
