The emerging role of NF2 alterations in new and established subtypes of renal cell carcinoma.

Hum Pathol 2022 Jun 12. Epub 2022 Jun 12.

Department of Pathology, University of Chicago, Pritzker School of Medicine, Chicago IL, Goldblatt Pavilion, 5841 S Maryland Ave, Chicago, IL 60637. Electronic address:

Genomic alterations are increasingly important in the current paradigms for the classification, diagnosis, and treatment of renal cell carcinoma. Bi-allelic alterations involving NF2 have been identified across a number of currently recognized subtypes of renal cell carcinoma including clear cell renal cell carcinoma and papillary renal cell carcinoma among others and may be associated with more a aggressive disease course as well as advanced stage at presentation. In addition, emerging evidence suggests the existence of a clinicopathologically distinct subset of renal cell carcinoma cases driven by bi-allelic loss of NF2 expression. Read More

Bilateral Gonadoblastoma in a 6-Year Old Girl With Frasier Syndrome: Need for Early Preventive Gonadectomy.

J Pediatr Hematol Oncol 2022 Jun 8. Epub 2022 Jun 8.

Third Department of Pediatrics.

Frasier syndrome (FS) is a rare condition, caused by splice-site mutations of intron 9 in the Wilms' tumor suppressor gene 1 (WT1 gene). The WT1 protein is essential for urogenital development and patients with 46XY karyotype present with female (FS type 1) or male phenotype, gonadal dysgenesis, progressive glomerulopathy, and high risk of gonadoblastoma. We describe a female patient with an IVS9+4C>T donor splice-site mutation, who underwent a preventive gonadectomy at the age of 6 years due to imaging findings of dysplastic gonads. Read More

Sex chromosome DSD individuals with mosaic 45,X0 and aberrant Y chromosomes in 46,XY cells: distinct gender phenotypes and germ cell tumour risks.

Syst Biol Reprod Med 2022 Aug 28;68(4):247-257. Epub 2022 Apr 28.

Department of Gynaecological Endocrinology & Infertility Disorders, Women Hospital, University of Heidelberg, Heidelberg, Germany.

")," individuals with rearranged Y chromosome breaks in their 46,XY cells are reported with male and female gender phenotypes and differences in germ cell tumour (GCT) risk. This raised the question of whether male or female gender and GCT risk depends on the site of the break and/or rearrangement of the individual´s Y chromosome. In this paper, we report molecular mapping of the breakpoint on the aberrant Y chromosome of 22 individuals with a 45,X/46,XY karyotype reared with a different gender. Read More

Recognition of the Y chromosome in Turner syndrome using peripheral blood or oral mucosa tissue.

Ann Pediatr Endocrinol Metab 2021 Dec 8;26(4):272-277. Epub 2021 Oct 8.

Division of Pediatric Endocrinology, Department of Pediatrics in Federal University of Sao Paulo (UNIFESP-EPM), Sao Paulo, Brazil.

Testosterone-induced increase in libido in a patient with a loss-of-function mutation in the AR gene.

Endocrinol Diabetes Metab Case Rep 2021 Jun 1;2021. Epub 2021 Jun 1.

Department of Service of Endocrinology, Diabetes, and Metabolism, Faculty of Biology and Medicine, University of Lausanne, Lausanne University Hospital, Lausanne, Vaud, Switzerland.

Summary: Complete androgen-insensitivity syndrome (CAIS), a disorder of sex development (46,XY DSD), is caused primarily by mutations in the androgen receptor (AR). Gonadectomy is recommended due to the increased risk of gonadoblastoma, however, surgical intervention is often followed by loss of libido. We present a 26-year-old patient with CAIS who underwent gonadectomy followed by a significant decrease in libido, which was improved with testosterone treatment but not with estradiol. Read More
