Recently, abnormalities of TBX4-FGF10-FGFR2-TMEM100 signaling regulating lung development have been reported in patients with AcDys due to heterozygous single-nucleotide variants or copy-number variant deletions involving TBX4, FGF10, or FGFR2. Here, we describe a female neonate who died at 4 hours of life due to severe respiratory distress related to AcDys diagnosed by postmortem histopathologic evaluation. Genomic analyses revealed a novel deleterious heterozygous missense variant c.728A>C (p.Asn243Thr) in TBX4 that arose de novo on paternal chromosome 17. We also identified 6 candidate hypomorphic rare variants in the TBX4 enhancer in trans to TBX4 coding variant. Gene expression analyses of proband's lung tissue showed a significant reduction of TMEM100 expression with near absence of TMEM100 within the endothelium of arteries and capillaries by immunohistochemistry. These results support the pathogenicity of the detected TBX4 variant and provide further evidence that disrupted signaling between TBX4 and TMEM100 may contribute to severe lung phenotypes in humans, including AcDys.","PeriodicalId":54634,"journal":{"name":"Pediatric and Developmental Pathology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11087193/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138479318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant comorbidities were seen in 13 patients (81%) and included: liver transplant (25%), history of a neoplasm (25%), autoimmune hepatitis (6%), Crohn disease (6%), bipolar disorder (6%), severe combined immunodeficiency (6%), and sickle cell disease (6%). Eleven patients were taking multiple medications at the time of biopsy. Granulomas were more commonly pan-acinar (11 cases) followed by subcapsular (4 cases), portal (1 case), and periportal (1 case). Necrosis was seen in 10 cases (59%). GMS stain was positive in 2 cases for Histoplasma-like yeast; microbiological cultures were negative in all cases (no: 4).

Dual immunolabeling was done to compare calretinin localization with markers of smooth muscle and interstitial cells of Cajal.Results: Calretinin expression was observed consistently in the innermost smooth muscle layers of the muscularis interna in the human cecum, appendiceal base, and proximal ascending colon, but not elsewhere in the intestinal tract. Calretinin-positive smooth muscle cells did not co-express markers located in adjacent interstitial cells of Cajal. Muscular calretinin immunoreactivity was not detected in the ceca of mice or macaques, species which lack appendices, nor in the rabbit cecum or appendix.Conclusions: Localized expression of calretinin in cecal smooth muscle cells may reduce the likelihood of retrograde, calcium-mediated propulsive contractions from the proximal colon and suppress pro-inflammatory fecal stasis in the appendix.","PeriodicalId":54634,"journal":{"name":"Pediatric and Developmental Pathology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140319932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
