case_images: The family history revealed the presence of presenile dementia, as the patient's mother died with severe dementia at the age of 59 years after a clinical history of approximately eight years (Fig. 1A). NGS sequencing of 25 dementia-associated genes identified the c.1301 C>T p.(Ala434Val) variant in the exon 12 of the Presenilin-1 (PSEN1; NM_000021.4) gene, confirmed by Sanger sequencing (Fig. 1B).
case_images: Neuroimaging findings. From left to right: CT, FDG-PET, and Amyloid PET with flutemetamol of the patient consistent with the diagnosis of PCA due to AD.
