Current approaches in CRISPR-Cas systems for hereditary diseases.
Prog Mol Biol Transl Sci

School of Health Sciences & Technology, UPES, Dehradun, Uttarakhand, India. Electronic address:
CRISPR-Cas technologies have drastically revolutionized genetic engineering and also dramatically changed the potential for treating inherited disorders. The potential to correct genetic mutations responsible for numerous hereditary disorders from single-gene disorders to complex polygenic diseases through precise DNA editing is feasible. The tactic now employed in CRISPR-Cas systems for treating inherited disorders is the usage of particular guide RNAs to target and edit disease-causing mutations in the patient's genome.

Breast cancer (BC) is a profoundly heterogenous disease, with diverse molecular, histological, and clinical variations. The intricate molecular landscape of BC is evident even at early stages, illustrated by the complexity of the evolution from precursor lesions to invasive carcinoma. The key for therapeutic decision-making is the dynamic assessment of BC receptor status and clinical subtyping.

Purpose: Constitutional mismatch repair deficiency (CMMRD) is a genetic cancer predisposition syndrome among children and young adults. This study aimed to evaluate the frequency of CMMRD among patients with pediatric high-grade glioma (pHGG) in a single tertiary care center in Pakistan, a country with high consanguinity rates.
Patients And Methods: We reviewed the data of patients age <18 years with pHGG, anaplastic astrocytoma, and diffuse midline glioma (DMG) with CMMRD testing between 2016 and 2023.
Los olvidados: Non-BRCA variants associated with Hereditary breast cancer in Mexican population.

Servicio de Oncología, Centro Universitario Contra el Cáncer (CUCC), Hospital Universitario "Dr. José Eleuterio González", Universidad Autónoma de Nuevo León, 66451, Monterrey, Nuevo León, México.
Background: Hereditary predisposition to breast and ovarian cancer syndrome (HBOC) is a pathological condition with increased cancer risk, including breast (BC), ovarian cancer (OC), and others. HBOC pathogenesis is caused mainly by germline pathogenic variants (GPV) in BRCA1 and BRCA2 genes. However, other relevant genes are related to this syndrome diagnosis, prognosis, and treatment, including TP53, PALB2, CHEK2, ATM, etc.

Background: Germline heterozygous pathogenic variants (PVs) in TP53 cause Li-Fraumeni syndrome (LFS), a condition associated with increased risk of multiple tumor types. As the associated cancer risks were refined over time, clinical criteria also evolved to optimize diagnostic yield. The implementation of multi-gene panel germline testing in different clinical settings has led to the identification of TP53 PV carriers outside the classic LFS-associated cancer phenotypes, leading to a broader cancer phenotypic redefinition and to the renaming of the condition as "heritable TP53-related cancer syndrome" (hTP53rc).
