DISCLAIMER
In general 70% of sSMC carriers are clinically normal. The figures listed above

are based on the bias, that mainly clinically aberrant cases are studied and reported in literature!

Cases with complex sSMC (Uc)

in {14} case 2 a complex sSMC is suggested after aCGH

however,  karyotype was
