Background: The phenotypic spectrum of muscle disease ranges widely from elevated creatine kinase (CK) levels in the serum of asymptomatic individuals to progressive muscular dystrophy. Due to overlapping clinical features among muscular dystrophies, the diagnosis of muscle disease is established by molecular genetic tests. Early diagnosis is crucial for the clinical management of symptoms and to mitigate cardiac and musculoskeletal complications.

While the etiology of SMS is commonly attributed to one-copy interstitial deletion in the 17p11.2 region (90-95% of cases), variants identified by sequence analysis in have also been reported in 5-10% of cases.

Methods: Trio WGS joint analysis was performed to investigate the genetic etiology in a proband with PWS, prolonged muscular hypotonia associated hyperCKemia, and early-onset obesity. The parents were unaffected.
Article Synopsis
- Tumors have unique genomic profiles that reveal specific mutations linked to DNA damage and repair processes, but germline genetic variants are often overlooked in this context.
- This study introduces a method to evaluate the significance of germline variants by combining somatic and germline genomic data, helping to reassess those variants in cancer patients with unusual or non-typical cancer traits.
- The integration of clinical criteria, somatic signatures, and tumor immunohistochemistry successfully re-classified variants of uncertain significance in various cancer types, emphasizing the need for a shared database to assess these variants more broadly in cancer research.
Article Synopsis
- * Current guidelines for assessing germline variants don't adequately incorporate data from tumors, which can be crucial for understanding their significance in cancer cases.
- * The authors present an optimized protocol that utilizes somatic tumor profiling to better evaluate the pathogenicity of germline variants, including details about case selection and key supporting evidence like loss of heterozygosity (LOH).
