Leveraging cancer mutation data to inform the pathogenicity classification of germline missense variants.
PLoS Genet
January 2025
Program in Genetics and Genome Biology, SickKids Research Institute, Toronto, Ontario, Canada.
Innovative and easy-to-implement strategies are needed to improve the pathogenicity assessment of rare germline missense variants. Somatic cancer driver mutations identified through large-scale tumor sequencing studies often impact genes that are also associated with rare Mendelian disorders. The use of cancer mutation data to aid in the interpretation of germline missense variants, regardless of whether the gene is associated with a hereditary cancer predisposition syndrome or a non-cancer-related developmental disorder, has not been systematically assessed.

Andes Pediatr
October 2024
Facultad de Ciencias de la Salud, Universidad Icesi, Cali, Colombia.
Unlabelled: Inherited Bone Marrow Failure syndromes account for approximately 25% of cases of aplastic anemia in pediatric patients. Next-generation sequencing (NGS) technologies have allowed the diagnosis of an increasing number of hereditary causes of bone marrow failure.
Objective: To determine the diagnostic yield and clinical concordance of NGS in the diagnosis of a cohort of pediatric patients with bone marrow failure.
Cerebrotendinous xanthomatosis: A complex interplay between a clinically and genetically heterogeneous condition.
Eur J Neurol
January 2025
Brain and Mind Centre, University of Sydney, Camperdown, New South Wales, Australia.
Background And Purpose: Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive lipid storage disease characterized by abnormal bile acid synthesis. It often presents with systemic and neurological manifestations; however, atypical presentations can lead to significant diagnostic challenges. This case report highlights the diagnostic complexities and management considerations in a patient with an uncommon presentation of CTX.

Eur J Hum Genet
January 2025
Department of Oncology-Pathology, Karolinska Institutet, BioClinicum, SE-171 77, Stockholm, Sweden.
We aimed to describe the clinical characteristics of families with heritable TP53-related cancer (hTP53rc) syndrome in Sweden with class 4 and 5 germline TP53 variants (gTP53), and to evaluate the genotype-phenotype correlation. These results were also used to evaluate our previously published phenotype prediction model based on TP53 missense variants and their impact on protein conformation. 90 families with hTP53rc were initially identified in Sweden.

Mol Genet Genomic Med
January 2025
Department of General Surgery, The Fourth Affiliated Hospital, China Medical University, Shenyang, Liaoning, China.
Background: Lynch syndrome (LS) is an autosomal-dominant disorder that increases the risk of many cancers. To identify novel or rare pathogenic variants of MMR genes associated with LS, especially in Chinese pedigrees.
Methods: One four-generation Chinese Han family from northeast China with 29 members was enrolled.
