Clinical profile, atrophy and inheritance patterns of pathogenic MAPT gene mutations in Frontotemporal dementia detected using whole exome sequencing: a single-center first report from India.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesFrontotemporal Dementia (FTD) is one of the common causes of early-onset degenerative dementia and is a clinically and pathologically heterogeneous group of neurodegenerative disorders. Globally, Microtubule Associated Protein Tau (MAPT), progranulin (GRN), and Chromosome 9 open reading frame 72(C9orf72) are the common FTD genetic mutations. However, they have not been reported from India, and only one progranulin (PGRN) mutation has been reported so far. This study aims to describe the clinical features and radiological patterns of seven patients of FTD harbouring pathogenic MAPT mutations from an Indian cohort of Frontotemporal dementia, using whole-exome sequencing (WES) for the first time.
methodsSubjects with dementia fulfilling the criteria for frontotemporal dementia were recruited from a teaching university hospital in South India. All of them underwent detailed clinical evaluation, neuroimaging, and genetic analysis by Whole Exome Sequencing (WES).
resultsAmong 86 patients with FTD who underwent WES, seven had MAPT mutations. Notably, two are novel variants.
conclusionIn the Indian context, pathogenic MAPT in FTD is being reported for the first time and notably from a single center by WES. Identifying pathogenic MAPT genes is important in planning mutation-specific clinical trials and understanding ethical and cultural differences in genetic FTD inheritance.
