Extractions: Author contact details Genomic imprinting is defined as the differential expression of a gene or chromosomal region according to the parental origin of inheritance. Both the maternal and paternal alleles are present, but while one is functionally active, the other is silenced (inactive) in somatic cells ( Fig. 1a Evidence for genomic imprinting of the maternal and paternal genomes The first evidence for genomic imprinting was provided by classical mouse experiments using the technique of pronuclear transplantation (Ref. ). Mouse embryos that were diploid but with the nuclear material derived solely from the maternal (gynogenetic) or paternal (androgenetic) genomes were created, but failed to develop post-implantation. In gynogenotes, development of the extraembryonic tissues was poor, although an embryo was present. Conversely, embryonic development in androgenotes was considerably retarded but substantial growth of the trophoblast and yolk sac was evident (Refs ). These experiments demonstrated that diploidy alone is not sufficient for normal embryonic development, but that both the maternal and paternal genomes are required. Furthermore, they showed that the maternal genome appears to be biased towards fetal development, whereas the paternal genome contributes more towards the development of extraembryonic structures (Ref.

Extractions: It is possible that the main title of the report Russell Silver Syndrome (RSS) is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report. Other physical findings associated with this disorder may include permanent fixation of the fifth fingers in a bent position (clinodactyly); webbing of the second and third toes (syndactyly); underdevelopment (hypoplasia) of certain bones of the fingers (phalanges); development of smooth, coffee-colored patches on the skin (cafe-au-lait spots); and/or abnormalities of the kidney and urinary tract. Most cases of Russell-Silver Syndrome are the result of new genetic changes (mutations) that occur randomly for no apparent reason (sporadic). If this mutation were to be inherited, it would do so as an autosomal dominant genetic trait. In rare cases, it is thought that the disorder may be inherited as an autosomal recessive genetic trait. In addition, a rare form of Russell-Silver Syndrome is thought to be inherited as an X-linked dominant genetic trait.

Extractions: My son has been fed though a gastrostomy since he was 3 months old and now he won't eat. He gets 1000 ml of 'Nutrini Extrain' his feeding pump at night but he's still underweight and doesn't put on weight well. He also has Silver-Russell Syndrome and a curved spine - could this have anything to do with it? If not, have you any suggestions on how to help? He is 5 yrs-old now, and I don't get any answers from anybody. David's advice Russell-Silver syndrome (RSS) has a number of recognised characteristics. Some individuals have many of the documented traits, while others have very few. Almost every individual with the syndrome has: Beyond this the characteristics vary very widely. However, the early years are often the most difficult and typically appetite will improve with age.

Prevention Definition: Rusell-Silver syndrome is a congenital disease (present at birth) characterized by short stature and, frequently, asymmetry in the size of the two halves or other parts of the body. Causes, incidence, and risk factors: Genetic problems are thought to cause this syndrome, although the specific gene(s) remain to be discovered. The pattern of inheritance has not been determined, but in most cases it seems to occur without any family history of the condition. Children with Russell-Silver syndrome are born small and generally achieve less than 5 feet at adult height. Side-to-side asymmetry is fairly common. For example, a left body part may be larger than the right counterpart. This asymmetry may occur anywhere including the face. Other characteristics include excessive sweating , a small triangular face that makes the skull look large by comparison, inward curving 5th fingers, and colored spots on the skin called cafe-au-lait spots
