Cases without clinical findings	Similar imbalances – no sSMC
Cases with clinical findings	Similar imbalances – no sSMC
der(13 or 21;18) syndrome
Cases without clear clinical correlation	Cases with discontinous sSMC
Cases with complex sSMC	Cases with UPD and sSMC
Cases (sSMC) with neocentromeres	Similar imbalances no sSMC
Tumor	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!

UPD (uniparental disomy) cases:	UPD(13)mat	UPD(13)pat	UPD(13)mat or pat
UPD (uniparental disomy) cases:	UPD(21)mat	UPD(21)pat	UPD(21)mat or pat
