And it has been found more frequently in infants with Patau syndrome (trisomy 13 with a Robertsonian translocation) (Aziz, 1980) and Edward syndrome (trisomy 18) at autopsy (Bersu & Ramirez-Castro, 1977).
A 13;21 Robertsonian translocation has been described in 2 cases, 1 each of skeletal MCS and EMCS.
Homozygosity for a Robertsonian Translocation (13q;14q) in an otherwise healthy 44, xy man with a history of repeated fetal losses.
This finding was further studied by molecular cytogenetics and confirmed robertsonian translocation rob (22;22) (Figure 2).

Molecular studies demonstrated that the ring included a duplicated region with a concomitant distal deletion suggesting the following mechanism: an initial Robertsonian translocation occurred between one paternal and one maternal chromosome in a trisomic cell, followed by distal breakage and deletion in both long arms of the translocation, leading to the formation of a ring chromosome.
There were two cases of trisomy 21 fetal karyotype coexistence with Robertsonian translocation in one case and Klinefelter sex CA in another case.
After cell-free DNA analysis became clinically available in 2011, ACOG and SMFM recommended it for women at increased risk of fetal aneuploidy, including women 35 years or older, fetuses with ultrasonographic findings indicative of an increased risk of aneuploidy, women with a history of trisomy-affected offspring, a parent carrying a balanced robertsonian translocation with an increased risk of trisomy 13 or trisomy 21, and women with positive first-trimester or second-trimester screening test results.
Embryos of robertsonian translocation carriers exhibit a mitotic interchromosomal effect that enhances genetic instability during early development.
The majority of cases (80%) are caused by the presence of an additional chromosome 13 owing to non-disjunction (usually in maternal meiosis I); ~10-20% are due to translocations, usually an unbalanced 13:14 Robertsonian translocation. [1]
Studies indicated that in the case of children having Trisomy 21 with Robertsonian translocation created sporadically de novo, the risk for a second future offspring trisomy 21 for their parents with normal karyotype is small.
