Translocation-specific polymerase chain reaction (PCR) detects de novo t(11;22)s in sperm from normal healthy males. We established a t(11;22)-specific PCR system utilizing sequence data from the junction fragments. PATRR-flanking primers were designed both on 11q23 and 22q11 to amplify the der(11) and the der(22) junction fragments .
The position of t(11;22)(q23;q11) constitutional translocation ... - PubMed
The t(11;22)(q23;q11) translocation is the most common recurrent balanced translocation described in humans. Carriers are phenotypically normal and often go undetected until diagnosis as a result of infertility investigations or following the birth of chromosomally unbalanced offspring.

2000年6月12日 · The t(11;22) is the most common recurrent non-Robertsonian constitutional translocation in humans, having been reported in more than 160 unrelated families. Balanced carriers are at risk of having offspring with the derivative 22 syndrome owing to 3:1 meiotic non-disjunction event.

2022年12月19日 · 2004年,Emanuel 综合征是以费城细胞遗传学家贝弗利·伊曼纽尔博士 (Dr Beverly Emanuel)的名字命名的,又称额外der (22)t (11;22)染色体综合征。 Emanuel 综合征发病率约为1/110 000。 迄今为止,全球已报道100余例。 + der (22)t (11;22)外显率为100%。 绝多数Emanuel 综合征是由 t (11;22) (q23;q11.2)易位携带者 配子发生过程中的异常减数分裂导致,t (11; 22) (q23; q11)是人类 最常见的复发性 非罗氏易位性染色体 ,其后代有 10% 风险为 Emanuel …
The constitutional t(11;22): implications for a novel mechanism ...
The constitutional t (11;22) (q23;q11) is the most common recurrent non-Robertsonian translocation in humans. The breakpoint sequences of both chromosomes are characterized by several hundred base pairs of palindromic AT-rich repeats (PATRRs).
Paternal origin of the de novo constitutional t(11;22)(q23;q11)
2010年2月24日 · Here, we have studied eight cases of de novo t (11;22) to determine the parental origin of the translocation using the polymorphisms on the relevant PATRRs. All of the eight translocations were...

The t(11;22)(q23;q11) translocation is the most common recurrent balanced translocation described in humans. Carriers are phenotypically normal and often go undetected until diagnosis as a result of infertility investigations or following the birth of chromosomally unbalanced offspring.
Fine mapping of the constitutional translocation t(11;22)(q23;q11)
Translocation t(11;22)(q23;q11) is the most common constitutional reciprocal translocation in man. Balanced carriers are phenotypically normal, except for decreased fertility, an increased spontaneous abortion rate and a possible predisposition to breast cancer in some families. Here, we report the …
