Tetrasomy 15q26: a distinct syndrome or Shprintzen-Goldberg syndrome phenocopy?

Abstract: Original research articlePurpose: The aim of this study was to characterize the clinical phenotype of patients with tetrasomy of the distal 15q chromosome in the form of a neocentric marker chromosome and to evaluate whether the phenotype represents a new clinical syndrome or is a phenocopy of Shprintzen-Goldberg syndrome. methods:We carried out comprehensive clinical evaluation of four patients who were identified with a supernumerary marker chromosome. The marker chromosome was characterized by G-banding, fl… Show more

“…To the best of our knowledge, up to now, 96 patients with chromosome 15q duplication have been reported in literature. Among these, 28 patients showed distal 15q tetrasomy due to a mosaicism or to a neocentromer marker chromosome (NMC) ( 2 , 3 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ) and the others had 15q distal trisomy ( 1 , 2 , 3 , 4 , 5 , 8 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ). The duplication of 15q chromosome can be classified in pure and impure forms, based on the presence of another chromosome abnormality (e.g.…”

“…Mutaciones de FBN1 también se ven en este síndrome, se ha identificado más de una mutación en el gen FBN1, causante de la enfermedad, y se heredan con un patrón autosómico dominante. (9,10) Aunque la mayoría de los casos reportados resultan esporádicos, únicos en su familia, también se han descrito familias con varios enfermos, (6) así como mosaicismo germinal, esto explica la aparición de más de un hermano enfermo de progenitores sanos. (10) El SGS es un trastorno del tejido conectivo raro.…”

“…Клиническое описание пациента, а также подробная характеристика всех ранее опубликованных преи постнатально диагностированных случаев частичной тетрасомии терминального района длинного плеча хромосомы 15 представлены в таблице 1. Изначально фенотипические проявления тетрасомии 15q связывали с «синдромом гипертрофии» (15q overgrowth syndrome, ORPHA:314585), однако недавно, благодаря работе Levy с соавт., была выделена отдельная синдромальная форма тетрасомии 15q26, с альтернативным названием «синдром Леви-Шанске» (Levy-Shanske syndrome: OMIM #614846) [8]. Levy с соавт.…”
