Brachydactyly is a genetic condition characterized by shortened or missing bones in the hands and feet. Several types of brachydactyly have been identified, each associated with different genetic mutations. However, some cases do not fit into existing classifications, necessitating further genetic investigation. A 34-year-old female patient with an absent middle phalanx in the second digit of her left foot and her 13-year-old son, who presented with absent or malformed middle and distal phalanx in all ten toes, are evaluated. Whole Genome Sequencing (WGS) analysis identifies a missense variant (c.1073A >T; p.K358M) in the BMP8A gene and a novel missense variant (c.1787C >T, p.Ser596Phe) in the FGFR1 gene. Functional protein association network analysis demonstrates a strong association of BMP8A and FGFR1 with other brachydactyly disease-causing genes. Given that these mutations have not been previously linked to any recognized brachydactyly subtype, they likely define a distinct genetic condition. The findings suggest a novel form of brachydactyly, which naming is proposed as brachydactyly type AB.</p>","PeriodicalId":72071,"journal":{"name":"Advanced genetics (Hoboken, N.J.)","volume":"6 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/ggn2.202500015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rooted in the discovery and characterization of natural photoreceptors, the field has advanced through the development of genetically encoded, light-sensitive proteins that enable precise spatiotemporal control of ion flux, intracellular signaling, gene expression, and protein interactions. This review traces key milestones in the emergence of optogenetics and highlights the development of major optogenetic tools. From the perspective of genetic tool innovation, the focus is on how these tools have been engineered and optimized for novel or enhanced functions, altered spectral properties, improved light sensitivity, subcellular targeting, and beyond. Their broadening applications are also explored across neuroscience, cardiovascular biology, hematology, plant sciences, and other emerging fields. In addition, current trends such as all-optical approaches, multiplexed control, and clinical translation, particularly in vision restoration are discussed. Finally, ongoing challenges are addressed and outline future directions in optogenetic tool development and in vivo applications, positioning optogenetics as a transformative platform for basic research and therapeutic advancement.</p>","PeriodicalId":72071,"journal":{"name":"Advanced genetics (Hoboken, N.J.)","volume":"6 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/ggn2.202500021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although biologics have been used in the clinic for more than eight decades, they are mostly unaffordable, thereby limiting their access to a large global population. The high cost is largely due to their production in cell culture systems (bacteria, yeast, CHO cells) requiring prohibitively expensive fermentation systems, purification of host cell proteins (>99%) to minimize allergic reactions, and instability of purified proteins requiring cold chain/transportation and invasive delivery through injections. Therefore, my lab pioneered the approach to develop recombinant proteins in edible plant cells that could be delivered orally via capsules or topically using chewing gums, eliminating the need for fermentation, purification, or cold chain. FDA approval of biologics bioencapsulated in plant cells has demonstrated a dramatic decrease in the cost of drugs (<5%) and a fraction of the regulatory cost for launching new drugs.
