The NTHL1 gene encodes DNA glycosylase, which is involved in base excision repair, and biallelic mutations of this gene result in NTHL1-associated polyposis (NAP), a hereditary disease characterized by colorectal polyposis and multiple types of carcinomas. However, no proper functional characterization of variant NTHL1 proteins has been done so far. Herein, we report functional evaluation of variant NTHL1 proteins to aid in the accurate diagnosis of NAP. Read More

The most important cause of developing hereditary breast cancer is germline mutations occurring in breast cancer (BCs) susceptibility genes, for example, BRCA1, BRCA2, TP53, CHEK2, PTEN, ATM, and PPM1D. Many BC susceptibility genes can be grouped into two classes, high- and low-penetrance genes, each of which interact with multiple genes and environmental factors. However, the penetrance of genes can also be represented by a spectrum, which ranges between high and low. Read More

We report a child with a past medical history notable for congenital deafness, palmoplantar keratoderma (PPK), and hypothalamic glioma who initiated a MEK inhibitor trametinib for cancer-directed therapy at 11 years of age and was incidentally noted to have marked improvement in his PPK. Trametinib withdrawal led to worsening in the patient's PPK. We speculate that the patient's PPK improved because of trametinib, given the temporal relationship between trametinib therapy and PPK severity, observed both after introduction and withdrawal of trametinib therapy.

Connexin36 (Cx36) forms gap junctions between neurons, which are called electrical synapses, enabling adjacent neurons to communicate directly. The participation of chemical synapses in neurodegeneration in amyotrophic lateral sclerosis (ALS) has long been indicated, but it remains unclear whether electrical synapses are involved in the pathogenesis of ALS. We performed extensive immunopathological analyses using mutant superoxide dismutase 1 (SOD1) transgenic mice and their littermates to investigate whether Cx36-made electrical synapses are affected in motor neuron diseases.

Advances in genomic research and risk-directed therapy have led to improvements in the long-term survival and quality of life outcomes of patients with childhood acute lymphoblastic leukaemia (ALL). The application of next-generation sequencing technologies, especially transcriptome sequencing, has resulted in the identification of novel molecular subtypes of ALL with prognostic and therapeutic implications, as well as cooperative mutations that account for much of the heterogeneity in clinical responses observed among patients with specific ALL subtypes. In addition, germline genetic variants have been shown to influence the risk of developing ALL and/or the responses of non-malignant and leukaemia cells to therapy; shared pathways for drug activation and metabolism are implicated in treatment-related toxicity and drug sensitivity or resistance, depending on whether the genetic changes are germline, somatic or both.

Multiple osteochondromas (MO) is a hereditary disorder associated with benign cartilaginous tumors, known to be characterized by absence or highly reduced amount of heparan sulfate (HS) in the extracellular matrix of growth plate cartilage, which alters proper signaling networks leading to improper bone growth. Although recent studies demonstrated accumulation of HS in the cytoplasm of MO chondrocytes, nothing is known on the structural alterations which prevent HS from undergoing its physiologic pathway. In this work, osteochondroma (OC), peripheral chondrosarcoma, and healthy cartilaginous human samples were processed following a procedure previously set up to structurally characterize and compare HS from pathologic and physiologic conditions, and to examine the phenotypic differences that arise in the presence of either exostosin 1 or 2 ( or ) mutations.
