Loss of heterozygosity (LOH) at chromosome 5 for each marker lesion combination in each of the haemangiomas (denoted UK1, UK2, and US1–4)

Haemangioma sample number

The results for each of the two dissections (L1 and L2) are given.
+inf, LOH was infinite owing to complete loss of one allele; –, the marker was uninformative or marker analysis was attempted but failed.
*LOH was greater than 2, denoting significant loss of the larger allele, or less than 0.5, denoting significant loss of the smaller allele.
The map location of each marker is taken from the Marshfield map set 8 from Research GeneticsTM.
