A study conducted by an international research team, which included investigators from Seattle Children’s Research Institute, implicates variants in four genes as a primary cause of non-syndromic cleft lip and palate in humans. The genes, associated for the first time with cleft lip and palate, encode proteins that work together in a network, providing important insight into the biological basis of one of the most common physical malformations.

Research in mice shows that a protein made by the stem cells that give rise to neurons, but not by neurons themselves, is key to brain cells’ ability to migrate during development and assume their proper positions. This primordial protein acts by clinging onto thousands of sites in the genome, affecting the activity of multiple genes that regulate brain development. The findings could yield valuable clues for a variety of neurodevelopmental disorders.

Approximately 47 million people worldwide are living with Alzheimer’s disease (AD) and other dementias. One of the most prominent neuroscientists in the country has developed eight myths and truths about AD to shed light on this form of dementia that causes problems with memory, thinking and behavior.

In an international Phase II trial led by researchers at The University of Texas MD Anderson Cancer Center, treatment with the oral FGFR inhibitor erdafitinib (ERDA) was well-tolerated and achieved a robust response for patients with metastatic urothelial, or urinary tract, cancers harboring mutations in the FGFR3 gene.

Matching targeted therapies to tumor-specific gene mutations across tumor types improved progression-free survival (PFS) and overall survival (OS) in patients with advanced disease relative to those receiving non-matched treatment (NMT), according to research from The University of Texas MD Anderson Cancer Center. The researchers also found that receiving matched targeted therapy (MTT) was an independent factor for predicting longer OS.

Roswell Park Comprehensive Cancer Center researchers have identified significant differences in the immune microenvironment of breast cancer tumors between African-American and white women, shedding light on the ways in which race can influence cancer development and outcomes. The findings, to be presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, are based on based on a comprehensive review of data from The Cancer Genome Atlas.

Cancer is one of the leading causes of death among Americans. At least 10 percent of cancers are caused by inherited mutations in genes such as BRCA1 and BRCA2. Parents with the cancer gene mutation have a 50 percent chance of passing it on to a son or daughter. It’s well-known that women with BRCA are at a very high risk for breast and ovarian cancer.
