Abstract

Mutations in the granulin gene (GRN) cause familial frontotemporal dementia. Understanding the structural brain changes in presymptomatic GRN carriers would enforce the use of neuroimaging biomarkers for early diagnosis and monitoring. We studied 100 presymptomatic GRN mutation carriers and 94 noncarriers from the Genetic Frontotemporal dementia initiative (GENFI), with MRI structural images. We analyzed 3T MRI structural images using the FreeSurfer pipeline to calculate the whole brain cortical thickness (CTh) for each subject. We also perform a vertex-wise general linear model to assess differences between groups in the relationship between CTh and diverse covariables as gender, age, the estimated years to onset and education. We also explored differences according to TMEM106B genotype, a possible disease modifier. Whole brain CTh did not differ between carriers and noncarriers. Both groups showed age-related cortical thinning. The group-by-age interaction analysis showed that this age-related cortical thinning was significantly greater in GRN carriers in the left superior frontal cortex. TMEM106B did not significantly influence the age-related cortical thinning. Our results validate and expand previous findings suggesting an

Abstract

A key symptom of frontotemporal dementia (FTD) is difficulty interacting socially with others. Social cognition problems in FTD include impaired emotion processing and theory of mind difficulties, and whilst these have been studied extensively in sporadic FTD, few studies have investigated them in familial FTD. Facial Emotion Recognition (FER) and Faux Pas (FP) recognition tests were used to study social cognition within the Genetic Frontotemporal Dementia Initiative (GENFI), a large familial FTD cohort of C9orf72, GRN, and MAPT mutation carriers. 627 participants undertook at least one of the tasks, and were separated into mutation-negative healthy controls, presymptomatic mutation carriers (split into early and late groups) and symptomatic mutation carriers. Groups were compared using a linear regression model with bootstrapping, adjusting for age, sex, education, and for the FP recognition test, language. Neural correlates of social cognition deficits were explored using a voxel-based morphometry (VBM) study. All three of the symptomatic genetic groups were impaired on both tasks with no significant difference between them. However, prior to onset, only the late presymptomatic C9orf72 mutation carriers on the FER test were impaired compared to the control group, with a subanalysis showing differences particularly in fear and sadness. The VBM analysis revealed that impaired social cognition was mainly associated with a left hemisphere predominant network of regions involving particularly the striatum, orbitofrontal cortex and insula, and to a lesser extent the inferomedial temporal lobe and other areas of the frontal lobe. In conclusion, theory of mind and emotion processing abilities are impaired in familial FTD, with early changes occurring prior to symptom onset in C9orf72 presymptomatic mutation carriers. Future work should investigate how performance changes over time, in order to gain a clearer insight into social cognitive impairment over the course of the

Abstract

En aquest treball es presenta l'evolució molecular i estudi funcional de gens localitzats a les duplicacions segmentàries de la regió 7q11.23, implicada en la Síndrome de Williams-Beuren (SWB). S'ha datat l'aparició d'aquestes duplicacions en els últims 25 milions d'anys d'evolució i s'ha proposat un model evolutiu amb reordenaments específics i mecanismes de generació. Correlacions clínico-moleculars en els pacients amb la SWB han permès determinar que l'haploinsuficiència per NCF1, un gen localitzat a les duplicacions, és un factor protector per hipertensió. S'ha proposat un model patogènic per la hipertensió, implicant l'oxidasa NAD(P)H i estrès oxidatiu, suggerint que noves estratègies terapèutiques podrien ser utilitzades. A més, s'ha caracteritzat parcialment la funció de GTF2IRD2, un altre gen de les duplicacions. GTF2IRD2 interacciona amb altres factors de transcripció relacionats, té una localització subcel·lular variable i no s'uneix a ADN. Aquests resultats contribueixen a conèixer millor els mecanismes mutacionals i patogènics de la SWB., This work presents the molecular evolution along with the functional analysis of the genes located in the segmental duplications flanking the 7q11.23 region, involved in Williams-Beuren syndrome (WBS). The generation of the segmental duplications has been dated to the last 25 million years of evolution and an evolutionary model with specific rearrangements and mechanisms has been proposed. Clinical-molecular correlations in WBS patients have allowed to determine that haploinsufficiency at NCF1, a gene located in the duplications, is a protective factor for hypertension. A pathogenic model for hypertension has been proposed, implicating NAD(P)H oxidase and oxidative stress, and suggesting that novel therapeutic strategies could be used. In addition, the functional characterization of another gene of the duplications, GTF2IRD2, has been partially achieved. GTF2IRD2 has been shown to interact with other related transcription factors, to display variable subcellular localization and to lack DNA binding properties. These results contribute to a better knowledge of the mutational and pathogenic mechanisms of the WBS.
