A consensus or society position rather than new primary data.
This narrative review discusses the current state and future directions of HSPC gene therapy for inherited hematologic disorders, highlighting lentiviral gene transfer, CRISPR-Cas editing, and ex vivo manipulation as emerging technologies with clinical promise. The source reports that recent clinical successes have demonstrated durable correction potential but identifies ongoing challenges including genotoxicity, conditioning toxicity, manufacturing scalability, and global access equity. This is expert synthesis and guidance rather than evidence from a primary trial.
Narrative review. Patients with inherited hematological disorders, particularly inborn errors of immunity and β-hemoglobinopathies.

Clinicians and researchers should recognize HSPC gene therapy as an advancing field with potential curative applications for select inherited hematologic disorders, while remaining aware of ongoing technical, safety, manufacturing, and equity challenges that must be resolved for broader clinical translation.
This is a narrative review synthesizing recent developments in HSPC gene therapy technologies, clinical outcomes, and future directions—expert guidance on the field rather than original evidence from a controlled trial.
As stated by the source record.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Hematopoietic stem and progenitor cells (HSPCs) gene therapy may transform the therapeutic landscape for inherited hematological disorders and already offers potentially curative options for some diseases, including inborn errors of immunity and β-hemoglobinopathies. Its continued success relies on further refinement of gene transfer technologies, gene editing tools such as CRISPR-Cas, and optimized ex vivo HSPC manipulation protocols that ensure robust, long-term engraftment and clonal diversity with reduced-toxicity, non-genotoxic conditioning strategies. Here, we review recent developments and refinements in gene transfer and editing technologies for HSPCs, while also discussing the critical limitations and hurdles to clinical translation, as recently presented at the New Investigator Committee Gene Therapy webinar. Future directions must prioritize integrating technological innovation with the development of equitable and simplified models to reduce costs and ensure that these life-saving cellular therapies reach patients worldwide. Teaser abstract Hematopoietic stem and progenitor cells (HSPCs) gene therapy is advancing rapidly, with lentiviral gene transfer, genome editing, and emerging in vivo delivery approaches expanding the therapeutic landscape for inherited hematologic disorders. Recent clinical successes have demonstrated the potential for durable correction, while ongoing refinements continue to improve safety, efficacy, and feasibility. Key challenges remain in genotoxicity, conditioning toxicity, manufacturing scalability, and equitable global access.
