摘要: We analyzed 53 loci on 21 chromosomes other than chromosome 4 to detect possible loss of heterozygosity in 31 thyroid tumors using polymorphic DNA markers that allelic deletions at specific chromosomal loci. Loss 1, 7 and 12 was detected one follicular adenoma, 1 two medullary carcinomas. However, no any the examined papillary These results suggest adenoma is signals for risk premalignant transformation, inactivation unknown genes 1p contributes tumorigenesis carcinoma. Some genetic changes losses may participate
