Proceeds these sales will benefit 11q. As many of you know I have two nephews with Jacobsen's syndome. Jacobsen's Syndrome (11q Deletion or 11q-) is a rare chrome disorder in which a portion of the 11th chromosome is missing. Through networking, cooperation with the research community, and the resulting sharing of information, their nonprofit will be better able to meet the challenges brought to parents, families and friends of 11q children.
