  　View Summary

  Multiple hereditary infundibulocystic basal cell carcinoma syndrome (MHIBCC), an autosomal dominant disorder caused by variants in SUFU, is characterized by numerous infundibulocystic basal cell carcinomas (IBCCs). In this report, we present a possible case of mosaic MHIBCC. A 57-year-old woman underwent the removal of four papules on her face, which were diagnosed as IBCCs. Exome sequencing revealed a SUFU c.1022+1G>A mutation within the skin tumor. The same mutation was detected in her blood but at a lower allele frequency. TA cloning revealed that the allele frequency of the mutation in the blood was 0.07. Additionally, tumor assessment revealed loss of heterozygosity (LOH) in chromosome 10, including the SUFU locus. These results indicate the patient had mosaicism for the SUFU mutation in normal tissues, aligning with the mosaic MHIBCC diagnosis. This, combined with LOH, likely contributed to IBCC development. Mosaic MHIBCC may present with milder symptoms. However, it may still increase the risk of developing brain tumors and more aggressive basal cell carcinoma. The possibility of mosaicism should be investigated in mild MHIBCC cases, where standard genetic tests fail to detect SUFU germline variants.

  　View Summary

  In this study, we analyzed the genes identified as candidate prognostic markers across carcinomas. Analysis of TCGA information in a database of clinical specimens showed that some candidate genes were up-regulated in some tumors, including breast cancer, and that the overall survival of the high expression group was significantly shorter than that of the low expression group. Quantitative PCR experiments using a breast cancer cell line cDNA also showed enhanced transcription of the gene. However, we counld not observe the protein translated from the gene. Thus, although this gene does not directly contribute to the malignant transformation of tumors, it is considered to be a valid marker of poor prognosis malignancy because elevated transcriptional levels correlate with shorter survival.

  Our group has provided the state of art genome technologies, named PAGS Support, including de novo genome sequencing, variation analysis, epigenomics, RNA analysis, metagenome analysis and single cell analysis, to the projects that were selected from proposals based on KAKENHI projects. Thus far, we have provided PAGS Support to altogether 912 proposals that were selected from 1988 proposals. The proposals cover the most fields of life sciences, expanding to the fields of physical sciences, environmental studies and so on. Thus far 556 papers have been published as the outcome, which covers from biology to agriculture, medicine and pharmacy, from basic to applied sciences. Our group has also developed new technologies and algorithms to overcome the problems emerged in the PAGS Support, which are used in the other PAGS Support projects. This is a positive cycle and therefore our system becomes a very effective way for the promotion of biological sciences.
