Electronic address:

Heterozygous missense variants and in-frame indels in SMC3 are a cause of Cornelia de Lange syndrome (CdLS), marked by intellectual disability, growth deficiency, and dysmorphism, via an apparent dominant-negative mechanism. However, the spectrum of manifestations associated with SMC3 loss-of-function variants has not been reported, leading to hypotheses of alternative phenotypes or even developmental lethality. We used matchmaking servers, patient registries, and other resources to identify individuals with heterozygous, predicted loss-of-function (pLoF) variants in SMC3, and analyzed population databases to characterize mutational intolerance in this gene.

Department of Preventive Population and Public Health Sciences, Keck School of Medicine and Norris Comprehensive Cancer Center, University of Southern California, 1450 Biggy Street, Los Angeles, CA 90033, United States.

Article Synopsis
  • Scientists looked at how certain genes may affect breast cancer in women with African ancestry.
  • They studied 9,241 women with breast cancer and compared them to 10,193 healthy women to find links between the genes and the disease.
  • They found specific gene variations that could increase the risk of breast cancer, especially types of cancer that don't depend on estrogen.

Article Synopsis
  • Lynch syndrome (LS) carriers develop certain types of tumors characterized by high rates of neoantigens, but information on targetable neoantigens from precancerous lesions is lacking, which is important for vaccine development.
  • Researchers sequenced genetic data from various stages of colorectal lesions in LS carriers to identify and rank the top 100 mutated neoantigens, validating their findings using specific laboratory assays.
  • The findings showed that while cancers and advanced precancers have numerous neoantigens, precancers exhibit fewer, with a significant proportion of the predicted neoantigens being able to prompt immune responses, suggesting potential for developing targeted vaccines against LS-related precancers and early-stage cancers.

Poly (ADP-ribose) polymerase inhibitors (PARPi) are used for patients with BRCA1/2 mutations, but patients with other mutations may benefit from PARPi treatment. Another mutation that is present in more cancers than BRCA1/2 is mutation to the TP53 gene. In 2D breast cancer cell lines, mutant p53 (mtp53) proteins tightly associate with replicating DNA and Poly (ADP-ribose) polymerase (PARP) protein.

Background: Previous work in European ancestry populations has shown that adding a polygenic risk score (PRS) to breast cancer risk prediction models based on epidemiologic factors results in better discriminatory performance as measured by the AUC (area under the curve). Following publication of the first PRS to perform well in women of African ancestry (AA-PRS), we conducted an external validation of the AA-PRS and then evaluated the addition of the AA-PRS to a risk calculator for incident breast cancer in Black women based on epidemiologic factors (BWHS model).

Methods: Data from the Black Women's Health Study, an ongoing prospective cohort study of 59,000 US Black women followed by biennial questionnaire since 1995, were used to calculate AUCs and 95% confidence intervals (CIs) for discriminatory accuracy of the BWHS model, the AA-PRS alone, and a new model that combined them.

Importance: There has been little consideration of genomic risk of recurrence by breast cancer subtype despite evidence of racial disparities in breast cancer outcomes.

Objective: To evaluate associations between clinical trial end points, namely pathologic complete response (pCR) and distant recurrence-free survival (DRFS), and race and examine whether gene expression signatures are associated with outcomes by race.

Design, Setting, And Participants: This retrospective cohort study used data from the Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging and Molecular Analysis 2 (I-SPY 2) multicenter clinical trial of neoadjuvant chemotherapy with novel agents and combinations for patients with previously untreated stage II/III breast cancer.

Unawareness of breast cancer family history among African women.

Pan Afr Med J

December 2023

Center for Clinical Cancer Genetics and Global Health, University of Chicago, Chicago, United States of America.

Introduction: comprehensive cancer risk assessment services are lacking in most sub-Saharan African countries and the use of accurate family history (FH) information could serve as a cheap strategy for risk evaluation. The aim of this study is to determine the proportion of women unaware of family history of cancer among female relatives and associated socio-demographic characteristics.

Methods: using case-control data on breast cancer among 4294 women in Nigeria, Uganda and Cameroon, we investigated the proportion of women unaware of family history of cancer among their female relatives.

Mahvash disease is an exceedingly rare genetic disorder of glucagon signaling characterized by hyperglucagonemia, hyperaminoacidemia, and pancreatic α-cell hyperplasia. Although there is no known definitive treatment, octreotide has been used to decrease systemic glucagon levels. We describe a woman who presented to our medical center after three episodes of small-volume hematemesis.

Article Synopsis
  • Lynch syndrome (LS) is a hereditary condition that increases the risk of colorectal and endometrial cancers, and this study explores the effects of a 12-month aerobic exercise program on LS patients' immune systems.
  • The trial involved 21 LS patients who participated in cycling classes three times a week for a year, and the results showed significant improvements in cardiorespiratory fitness and reduced inflammation markers compared to a control group.
  • The exercise group experienced changes in immune cell profiles in their colon, suggesting that regular exercise may help lower cancer risk in LS patients by affecting their immune system.

Purpose: There exists a barrier between developing and disseminating risk prediction models in clinical settings. We hypothesize this barrier may be lifted by demonstrating the utility of these models using incomplete data that are collected in real clinical sessions, as compared to the commonly used research cohorts that are meticulously collected.

Latent class symptom profiles of colorectal cancer survivors with cancer-related cognitive impairment.

Support Care Cancer

September 2023

Center for Healthy Aging, Self-Management and Complex Care, Ohio State University, College of Nursing, Columbus, OH, USA.

Article Synopsis
  • Colorectal cancer (CRC) survivors often face cognitive impairment and various symptoms post-treatment, but there's limited knowledge about the risk factors influencing these complex symptom patterns.* -
  • The study identified three groups of CRC survivors based on symptom profiles: one with low symptoms, one with high psychological symptoms like depression and anxiety, and another with high somatic symptoms (fatigue, sleep issues, and pain) along with cognitive impairment.* -
  • Findings indicate that those with a high symptom burden tend to have a shorter time since diagnosis, higher perceived stress, and poorer emotional social support, highlighting the need for better screening and targeted interventions for these issues.*

Purpose: LFSPRO is an R library that implements risk prediction models for Li-Fraumeni syndrome (LFS), a genetic disorder characterized by deleterious germline mutations in the gene. To facilitate the use of these models in clinics, we developed LFSPROShiny, an interactive R/Shiny interface of LFSPRO that allows genetic counselors (GCs) to perform risk predictions without any programming components, and further visualize the risk profiles of their patients to aid the decision-making process.

Methods: LFSPROShiny implements two models that have been validated on multiple LFS patient cohorts: a competing-risk model that predicts cancer-specific risks for the first primary, and a recurrent-event model that predicts the risk of a second primary tumor.
