Duplication of a small segment of 5p due to maternal recombination within a paracentric shift

Abstract
Duplication of chromosome sub‐bands 5p14.3 and 5p15.1 in a child resulted in mild mental retardation, apparently without other abnormalities. The duplicated region arises from recombination within a directly inserted segment following a shift within the short arm of the maternal chromosome 5 homologs.
