Osteocondrodisplasia de tipo displasia campomélica / Osteochondrodysplasia of campomelic dysplasia type

La osteocondrodisplasia de tipo displasia campomélica es una alteración del desarrollo esquelético que se presenta de forma autosómica dominante. Se caracteriza por la angulación de las extremidades, junto con otras alteraciones, cardiopulmonares, orofaciales y neurológicas. Las mutaciones estudiadas presentes en el gen SOX9 son responsables de la mayoría de casos de estas alteraciones. Se presenta aquí un caso de displasia campomélica hijo de madre de 22 años con embarazo de 24 semanas.

Campomelic dysplasia (CD) is a type of osteochondrodysplasia or disorder of skeletal development with autosomal dominant inheritance. It is characterized by angulation of the limbs along with cardiopulmonary, orofacial and neurological alterations. Mutations involving the SOX9 gene are responsible for CD in most affected individuals. A case of CD is presented in a boy born at 24 weeks of gestational age to a 22-year-old mother.

Reporte de caso de síndrome FATCO: aplasia fibular, campomelia de tibia y oligosindactilia / A case report of a patient with FATCO syndrome: fibular aplasia, tibial campomelia and oligosyndactyly

El síndrome FATCO, por las siglas en inglés de aplasia fibular (Fibular Aplasia), campomelia de tibia (Tibial Campomelia) y oligosindactilia (Oligosyndactyly), es un conjunto de malformaciones óseas, en las que la alteración se centra en los huesos de la pierna. Es una entidad rara y hay pocos casos descritos en la Literatura internacional, y, hasta ahora, no se ha descrito ningún caso en Colombia. Presentamos aquí el caso de un recién nacido de sexo masculino con signos clínicos de manera prenatal y posnatal consistentes con síndrome FATCO sin otras malformaciones asociadas. Exponemos también una breve discusión sobre las diferentes malformaciones óseas y otros casos de FATCO en el mundo.

The FATCO syndrome, (Fibular Aplasia, Tibial Campomelia and Oligosyndactyly) are bone malformations with main alteration in lower limbs. It is a rare entity and there are few cases reported in international literature, and so far there are not published cases in Colombia. Here we present a case of a male newborn with prenatal and postnatal signs consistent with FATCO syndrome without other organs malformations, and there is a brief discussion about this syndrome and other different malformations associated with it.

A Korean Girl with Campomelic Dysplasia caused by a Novel Nonsense Mutation within the SOX9 Gene

Campomelic dysplasia (CMD) is a rare, often lethal, genetic disorder characterized by multiple congenital anomalies and abnormal development of the reproductive organs in males. Mutations in the SOX9 gene are known to cause CMD. We present a Korean CMD girl with a normal 46,XX karyotype and a female reproductive organ phenotype. She was born at 2.35 kg at 38 weeks of gestation and showed characteristic phenotypes, including cleft palate, micrognathia, hypertelorism, flat nasal bridge, congenital bowing of limbs, hypoplastic scapulae, deformed pelvis, and 11 pairs of ribs. She also had an atrioseptal defect of the heart and marked laryngotracheomalacia requiring tracheostomy and tracheopexy. SOX9 mutation analysis revealed the presence of a novel nonsense mutation, p.Gln369*, and the patient was genetically confirmed to have CMD. Although she showed marked failure to thrive and neurodevelopmental delay, she is now 40 months of age and is the only surviving patient with CMD in Korea.

A Case of Campomelic Dysplasia without Sex Reversal

Campomelic dysplasia (CD; OMIM #114290), a rare form of congenital short-limbed dwarfism, is due to mutations in SOX9, a member of the SOX (SRY-related HMG box) gene family. Multiparous mother at 38 weeks' gestation delivered a 3,272 g baby boy with characteristic phenotypes including bowing of the lower limbs, a narrow thoracic cage, 11 pairs of ribs, hypoplastic scapulae, macrocephaly, flattened supraorbital ridges and nasal bridge, cleft palate, and micrognathia. He underwent a tracheostomy at the age of three months for severe laryngomalacia after a number of repeated hospitalizations due to respiratory problems and died at the age of four months from progressive respiratory failure. He was diagnosed as having CD based on a novel frameshift mutation (p.Gln458ArgfsX12) in the SOX9 gene, the mutation which has not yet been reported in Korea.

Displasia esquelética campomélica: reporte de caso / Campomelic dysplasia: case report

La displasia campomélica es una osteocondrodisplasia poco frecuente, incluida dentro del grupo de las osteocondrodisplasias letales. Su origen genético son mutaciones en el gen SOX9 que se heredan de forma autosómica dominante. Se caracteriza clínicamente por la forma arqueada de las extremidades, malformaciones de la caja torácica, alteraciones cartilaginosas en el árbol traqueobronquial, alteraciones en la diferenciación genital y otras anomalías menores. Los pacientes con este diagnóstico no tienen un buen pronóstico, a pesar de instaurarse un manejo adecuado. Usualmente, la muerte se da en el período neonatal por insuficiencia respiratoria, debido a las malformaciones torácicas, aunque se describen casos con buen pronóstico. El diagnóstico temprano in utero, a través de la ecografía prenatal y la confirmación diagnóstica con radiografía convencional, son indispensables para un adecuado abordaje interdisciplinario del paciente. Se presenta el caso de un recién nacido masculino con displasia campomélica y su abordaje diagnóstico desde la radiología.

Campomelicdysplasia is a rare osteochondrodysplasia, which is included in the lethal osteochondrodysplasias group. Mutations in SOX9 gene are responsible for this disorder and its inheritance mechanism is autosomal dominant. Campomelicdysplasia is characterized by congenital bowing and angulations of long bones, tracheobronchial tree abnormalities, ambiguous genitalia, dislocated hips and other minor abnormalities. Prognosis is poor in spite of suitable management. Death is usually produced by respiratoryfailure due to thoracic malformations. The early in utero diagnosis through prenatal ultrasonography and its confirmation by conventional X–ray are both essential for an interdisciplinary management. We present a case of a male newborn with campomelicdysplasia and its radiological diagnostic approach.

A case of fetal skelectal anomaly of Campomelic syndrome / 대한산부인과학회잡지

Campomelic syndrome is a very rare skeletal dysplasia with a characteristic pattern of deformity involving the proximal and distal extremities, pelvic and shoulder girdles, thoracic cage and palate. Respiratory compromise often leads to death in early infancy. Etiology has not been determined although evidence suggests genetic heterogeneity. Cytogenetic study revealed high incidence of a 46,XY karyotype in phenotypic females. Recently, we had experienced a case of campomelic dysplasia at amenorrhea 30weeks and termination was done, so we report with a brief review of literature.
