Chromosome 8-derived supernumerary ring/marker is a rare chromosomal anomaly comprising variable parts of chromosome 8. The phenotype of mosaic or non-mosaic supernumerary r(8)/mar(8) ranges from almost normal to variable degrees of minor abnormalities, and growth and mental retardation overlapping with the well-known mosaic trisomy 8 syndrome (see this term).

Deviated fingers is a term that should be used if one or more fingers of the hand are deviated from their normal position, either to the radial or ulnar side. A deviation of a finger can be caused by an abnormal form of one or more of the phalanges of the affected finger, or by a deviation or displacement of one or more phalanges.
