Interstitial deletions of the long arm of chromosome 5 involving the region 5q33.1-q34 are rare occurrences. The clinical features of patients carrying similar deletions include dysmorphic facial features, such as epicanthus, retrognatia, protruding left ear and asymmetric mouth, high-arched palate, four inger lines and clinodactyly of digits II and V on both hands. We report on a female child aged 13 presentin...
Com o avanço das técnicas de Procriação Medicamente Assistida (PMA), surgiu em 1990 a primeira criança nascida após diagnóstico genético pré-implantação (DGPI). Neste tipo de análise, após estudo feito geralmente entre o terceiro e o quinto dias pós-fertilização, os embriões não afetados são transferidos para o útero materno. O DGPI, apesar de necessitar de técnicas relativamente recentes e dispendiosas, oferec...
Introdução – Cromossomas derivativos são o resultado de rearranjos estruturais que tanto podem ocorrer num só, como entre dois ou mais cromossomas. Estes rearranjos dão origem a cromossomas estruturalmente anormais, podendo resultar um fenótipo normal ou mais ou menos grave, dependendo do tipo de anomalia encontrada. Materiais e métodos – Caso índex: homem de 55 anos, referenciado para estudos de citogenética c...
Mental retardation (MR) is a major social, educational, and health problem affecting 3% of the population. Subtelomeric chromosome aberrations are one of the major causes of MR with or without multiple anomalies; previous studies have shown that these rearrangements are responsible for 3-6% of unexplained mental retardation. Between 2000-2010 in the Cytogenetics Unit, Centro de Genética Médica Jacinto de Magal...
Poster: 10.P7 ; Chromosomal rearrangements involving three break-points are relatively rare, about 1/5,000 live births. When a chromosomal segment is moved from one part of a chromosome into another part of the same chromosome, it is considered an intrachromosomal insertion; the orientation of the inserted material in relation to the centromere may remain the same, resulting in a direct insertion, or reversed,...
Chromosome 1p36 deletion syndrome (MIM #607872) was first described in 1997 by Shapira et al. This condition is compatible with a monosomy of the 1p36 band in the distal region of the short arm of chromosome 1 and is the most common terminal deletion in humans, with an estimated prevalence of approximately 1 in 5,000 live births. This constitutional deletion is associated with mental retardation, developmental...
Interstitial deletions of chromosome 13 are known to be associated with retinoblastoma. A wider syndrome may accompany the deletion, including mental retardation and craniofacial dysmorphism. The severity of the phenotype depends on the extent of the deletion. Retinoblastoma is a malignant tumor in the retina and is the most common ocular cancer in children. The association of most cases of retinoblastoma with ...
