Further studies of a Kindred having an aberrant autosome (13-15) without apparent phenotypic effect

Abstract

A girl and her father, both apparently normal, had been reported earlier as carriers of a satellited submetacentric chromosome in place of a long acrocentric chromosome. A morphologically identical chromosome has now been found in the proposita's paternal uncle, but in neither a paternal cousin nor a paternal great uncle. Clinical studies of the proposita did not reveal any deviations from normality.
