From: Small supernumerary marker chromosomes (sSMC) in humans; are there B chromosomes hidden among them
The shape of familial sSMC is summarized according to the sSMC homepage. In non-acrocentric chromosome-derived sSMC (sSMC(n-acro)) only ring (r) and minute (min) chromosomes are to be observed, in acrocentric chromosome derived sSMC (sSMC(acro)) predominantly inverted duplication (inv dup) followed by minute and ring chromosomes are present. The abbreviation 'min' is applied here according to the definition of 'minute chromosome' of Crolla (1998).
