Microsatelite analysis on 15q11-q13 of proband and parents. The markers are shown in order from the centromere towards the telomere. Those markers highlighted in bold indicate paternal UPD. The sex averaged genetic distances from the centromere are taken from Robinson and Lalande.17 Allele status in the proband is shown in the last column
