Ítem Síndrome de pterigium múltiple letal: reporte de caso(Sociedad Chilena de Obstetricia y Ginecologia, 2013-01-01) Ruiz Botero, FelipeEl Pterigium múltiple letal es una condición heredada, la cual se caracteriza por la presencia de pterigium articulares, contracturas en flexión, asociadas a otros defectos como retraso del crecimiento intrauterino, hydrops fetal, higroma quístico, artrogriposis y pulmones hipoplásicos. La etiología de esta condición son mutaciones homocigotas o compuestas heterocigotas en el gen CHRNG, locust 2q37.1, el cual codifica la subunidad gamma del receptor de acetilcolina (AChR). Se reporta un caso de pterigium múltiple letal, con las características clásicas, que tuvo diagnóstico prenatal de rigidez e imposibilidad de movimiento pasivo de las extremidades. Este es el primer caso reportado en Colombia en una institución nivel III de la ciudad de Cali.Ítem Síndrome de duplicación del cromosoma 7q11.23. En primer lugar reportado casos en América Latin(2016-02-01) Ruiz Botero, Felipe7q11.23 duplication syndrome is a disease caused by duplication of a region of chromosome 7 comprising 26 genes. The first case described in the literature was reported by Somerville et al. in 2005, who described a patient with dolichocephaly, high and narrow forehead, long eyelashes, high and wide nose, short philtrum, high arched palate, dental malocclusion, retrognathia, and severe language delay. We report the case of a Colombian patient with 7q11.23 duplication by comparative genomic hybridization techniques, and classical clinical findings, this being the first reported case in Colombia and Latin America. El síndrome de duplicación 7q11.23 es una patología causada por la duplicación de una región del cromosoma 7 que comprende 26 genes. El primer caso descrito en la literatura fue reportado por Somerville et al., en el año 2005, quienes describieron un paciente con dolicocefalia, frente alta y estrecha, pestanas largas, nariz alta y ancha, filtrum corto, paladar ojival, maloclusión dental, retrognatia y retardo grave en el lenguaje. Presentamos una paciente colombiana con hallazgo de duplicación 7q11.23 mediante técnicas de hibridación genómica comparativa y hallazgos clínicos clásicos. Este es el primer caso comunicado en Colombia y en América Latina.Ítem Novel PORCN mutation in a severe case of Focal Dermal Hypoplasia(Wiley-Blackwel, 2016-05-01) Pachajoa Londoño, Harry MauricioFocal dermal hypoplasia is a rare genetic disease characterized 8-year-old female who sought genetic counseling for multiple malformations, aggressive behavior and intellectual disability. Gene analysis confirmed focal dermal hypoplasia.Ítem Secuencia de Poland, de las bases embriológicas a la práctica clínica(Editorial Ciencias Medicas, 2015-07-14) Ruiz Botero, FelipePoland sequence is a birth defect typically described as unilateral congenital absence of the pectoralis muscle, which may be associated with the occurrence of other ipsilateral thoracic and/or upper extremities anomalies that cover different degrees of functional severity and esthetic alterations. The literature describes various types of association with different syndromes; however, its etiology remains unknown and several hypotheses about the possible cause of this disease exist, being the most accepted the one that deals with vascular disruption processes. In the clinical practice, mild forms of expression can be ignored, but in the most severe cases, the attention of a multidisciplinary group of specialists is required for disease management. A systematic literature review on Poland sequence was made.Ítem Fatal respiratory disease due to a homozygous intronic ABCA3 mutation: A case report(BioMed Central, 2016-09-26) Padilla, IvánPulmonary surfactant is a complex mixture of lipids and proteins. Mutations in surfactant protein-C, surfactant protein-D, and adenosine triphosphate-binding cassette subfamily A member 3 have been related to surfactant dysfunction and neonatal respiratory failure in full-term babies. Adenosine triphosphate-binding cassette subfamily A member 3 facilitates the transfer of lipids to lamellar bodies. We report the case of patient with a homozygous intronic ABCA3 mutation. Case presentation: We describe a newborn full-term Colombian baby boy who was the son of non-consanguineous parents of mixed race ancestry (Mestizo), who was delivered with severe respiratory depression. Invasive treatment was unsuccessful and diagnosis was uncertain
