In most cases, this biological tissue is characterized by the presence of tumor cells characterized by instability and loss of heterozygosity of microsatellites (MSI\/LOH) compared to the DNA present in cells of normal tissue.In this case report, two FFPE samples from the same male subject were available for genetic investigation: one sample with colorectal cancer tissue and the other with normal tissue (no cancerous histopathological features). The comparison of the genetic profiles obtained from DNA extracted from the two tissues showed in the tumor tissue the presence of three genomic instability phenomena affecting FGA, CSF1P0, D21S2055 loci, located on three distinct autosomal chromosomes, and one duplication phenomenon affecting the DYS438. Therefore, due to the MSI\/LOH phenomena, the genetic profile acquired from the tumor tissue was distorted and thus generated a fictitious genetic profile, not corresponding to the subject\u2019s real one (normal tissue free of tumor cells).<\/jats:p>","DOI":"10.1007\/s00414-024-03341-w","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T03:02:54Z","timestamp":1728356574000},"page":"61-65","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unveiling STRs instability in a colorectal cancer FFPE sample: a case report"],"prefix":"10.1007","volume":"139","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7442-8139","authenticated-orcid":false,"given":"Giulia","family":"Soldati","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiara","family":"Saccardo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dario","family":"Raniero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico","family":"De Leo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefania","family":"Turrina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,10,8]]},"reference":[{"issue":"1","key":"3341_CR1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1016\/j.forsciint.2004.03.006","volume":"145","author":"M Poetsch","year":"2004","unstructured":"Poetsch M, Petersmann A, Woenckhaus C, Protzel C, Dittberner T, Lignitz E, Kleist B (2004) Evaluation of allelic alterations in short tandem repeats in different kinds of solid tumors-possible pitfalls in forensic casework.
