ABSTRACT
El Síndrome de Progeria de Hutchinson- Gilford es una enfermedad que se caracteriza por el envejecimiento prematuro en niños, debido a una mutación en el gen de Lámina tipo A involucrado en la mitosis celular. En el presente trabajo, con el objetivo de dar difusión al conocimiento de esta enfermedad, se señalan los procesos involucrados en su desarrollo, así como los avances científicos y el alcance de nuevas ventanas terapéuticas. La revisión se realizó consultando artículos en español e inglés empleando los motores de búsqueda Pubmed y Google Académico. La actualización del personal de salud sobre las enfermedades genéticas congénitas es de vital importancia para mejorar su detección, atención y manejo.

ABSTRACT
Abstract Isolated left ventricular apical hypoplasia is a rare cardiomyopathy, with a broad range of clinical presentations. Since this entity was already described in association with osteomuscular diseases, mutation in the Lamin A/C gene has been regarded as a possible cause of this disease. This study describes the case of an asymptomatic teenager with isolated left ventricular apical hypoplasia and arthrogriposis but with no mutations in the entire Lamin A/C gene.

INTRODUCTION: Kobberling-Dunnigan syndrome is characterized by a series of alterations in metabolism and body fat distribution. Body dysmorphism and the Cushingoid appearance may have negative social and psychological impacts on the patient, including difficulty with social adaptation. In such cases, liposuction is used with the aim of improving body contour, with consequent improvements in self-esteem. The results are long lasting when body weight is maintained. CASE REPORT: Liposuction of the back, abdomen, and cervical regions in a woman with Kobberling-Dunnigan syndrome led to significant improvement in her body shape, and the results were maintained nine months postoperatively.
INTRODUÇÃO: A síndrome de Kobberling-Dunnigan caracteriza-se por um conjunto de alterações metabólicas e de distribuição da gordura corporal. O dismorfismo corporal e o aspecto cushingoide trazem repercussões psicológicas e sociais, com dificuldade de ajuste social. Nesses casos, a lipoaspiração é empregada com o objetivo de melhorar o contorno corporal e, consecutivamente, as alterações de autoestima. Os resultados apresentam-se duradouros quando há manutenção do peso. RELATO DO CASO: Paciente do sexo feminino, portadora de síndrome de Kobberling-Dunnigan, submetida a lipoaspiração de dorso, abdome e região cervical, com melhora significativa do contorno corporal e manutenção dos resultados nove meses após a operação.

Objective :The Hutchinson-Gilford progeria syndrome (HGPS or progeria) is a childhood disorder with features of premature aging and is caused by mutations in the lamin A gene resulting in the production of an abnormal protein, termed progerin. To investigate the underlying pathogenic mecha-nism, we studied the nuclear co-localization and association of progerin interactive partner proteins (PIPPs) with lamina proteins. Methods:Both wild-type (WT) and progeria fibroblasts were studied by various methods including eonfocal microscopy, immunopreeipitation and Western blot. Results:All PIPPs discovered so-far co-localized with lamin A/C. In addition, the PIPPs were selectively associated with lamina proteins. An increased immunofluorescent staining signal was found for Mel18 in HGPS as com-pared to WT cells. An association of Me118 with emerin was observed in HGPS, but not in WT cells.Conclusion: Based on these findings, we propose that PIPPs, along with associated lamina proteins may form a pathogenic progerin-containing protein complex.
