Advances in molecular diagnostic techniques have expanded our ability to detect a broad spectrum of DMD variants, including exonic deletions/duplications, small variants such as single-nucleotide variants and indels, and intronic rearrangements that disrupt splicing. Transcriptomic and long-read genomic analyses have revealed previously undetectable mechanisms of variation, including pseudoexon inclusion, intronic polyadenylation, and repeat expansions, underscoring the importance of integrating RNA-level data and in silico predictions into diagnostics. Genotype-phenotype correlations are influenced by the type and location of variants and by other factors, such as naturally occurring exon skipping and modifier genes. For instance, partial dystrophin expression caused by exon skipping in patients with certain nonsense variants can result in a milder Becker-like phenotype. These findings highlight the clinical significance of functional assays, such as minigene splicing reporters and immunostaining, in refining variant interpretation. This review summarizes the spectrum of DMD variants and outlines a stepwise diagnostic approach that integrates genetic, transcriptomic, and computational data. Special consideration is given to subgroups, such as female carriers and patients with mild phenotypes, in whom molecular diagnosis can be particularly challenging.

CDG comprise a heterogeneous group of diseases caused by defects at various stages of the glycosylation pathway. Each year, new types of CDG are identified, and to date, pathogenic variants in 189 genes have been associated with over 200 distinct human glycosylation-related disorders. Each type of CDG exhibits characteristic clinical features. Many of CDG result in multisystem involvement, with the central nervous system being particularly affected. Clinical manifestations are highly variable and may include developmental delays, growth impairment, neurological abnormalities such as ataxia, hepatic dysfunction, cardiac defects, coagulation disorders, and abnormal fat distribution. In patients with unexplained neurological symptoms, it is now standard practice to include CDG in the differential diagnosis. Detection of altered glycosylation patterns in serum proteins is essential in the diagnostic evaluation of CDG. Analytical techniques allow the identification of defects in N-glycosylation, O-glycosylation, and combined glycosylation pathways. Once abnormalities in glycosylation are detected, subsequent genetic analysis is necessary to identify causative variants. Our research institute has contributed to the CDG diagnostic support center in Japan by developing novel analytical methods utilizing mass spectrometry.

There is currently no effective treatment for this skeletal disease. This study proposes a novel lentiviral vector (LV)-based gene therapy that produces and secretes the active GALNS enzyme at supraphysiologic levels within the cells. LVs carrying the native GALNS encoding sequence (cDNA) were made under three different promoters: CBh, COL2A1, and CD11b. Moreover, we designed LVs carrying the native GALNS cDNA tagged with D8 octapeptide under the CD11b promoter and a human codon-optimized GALNS cDNA under the CBh promoter, respectively. Transduced HEK293 cells, HepG2 cells, and MPS IVA fibroblasts and chondrocytes were cultured for 8 and 30 days, and the media were collected every three days. The enzyme activity, GAG levels, and vector copy numbers (VCNs) in these cells and media were analyzed. LV with the COL2A1 promoter produced the highest enzyme activity in HEK293, HepG2, MPS IVA fibroblasts, and chondrocytes, followed by LV with the CBh promoter. VCNs were higher in MPS IVA fibroblasts treated with LV-CBh-hGALNS and in HepG2 cells treated with LV-CD11b-hGALNS than in HEK293 cells. Accumulated GAGs were normalized to wild-type levels by the LV gene therapy, especially with CBh and COL2A1 promoters.

The results showed that 1.1% of CHD patients had laterality defects (206/18,781), with 0.4% presenting as situs inversus totalis and 0.7% as situs ambiguus. The prevalence of laterality defects was higher in complex CHD cases (5.4%) compared to simple CHD (0.4%).
