Mutations in the prion-like domain (PrLD) of hnRNPA1 and A2/B1 genes were recently identified in 2 families with inclusion body myopathy associated with Paget disease of bone, frontotemporal dementia (FTD), and amyotrophic lateral sclerosis, and in ALS patients. These mutations were shown to increase the propensity of hnRNPA1 and A2/B1 proteins, which are(More)
Schizophrenia (SZ) and bipolar disorder (BPD) are two severe psychiatric diseases with a strong genetic component. In agreement with the 'continuum theory', which suggests an overlap between these disorders, the existence of genes that affect simultaneously susceptibility to SZ and BPD has been hypothesized. In this study we performed a 7.5 cM genome scan(More)
OBJECTIVE To carry out a deep characterisation of the main androgen-responsive tissues involved in spinal and bulbar muscular atrophy (SBMA). METHODS 73 consecutive Italian patients underwent a full clinical protocol including biochemical and hormonal analyses, genitourinary examination, bone metabolism and densitometry, cardiological evaluation and(More)
The present study aims at investigating the association between common and rare variants of mitochondrial DNA (mtDNA), and increased risk of schizophrenia (SZ) and bipolar disorder (BPD) in a cohort of patients originating from the same Italian population. The distribution of the major European mtDNA haplogroups was determined in 89 patients and their(More)
X-linked hydrocephalus, MASA syndrome, X-linked complicated Spastic Paraplegia Type I and X-linked partial agenesis of the corpus callosum are the four rare diseases usually referred to L1 syndrome, caused by mutations in the L1CAM gene. By direct sequencing of L1CAM in 16 patients, we were able to identify seven mutations, five of which were never(More)
X-linked Charcot-Marie-Tooth disease is the second most common variant of CMT. CMTX1 is caused by mutations in the GJB1 gene encoding for connexin 32. We describe an Italian family with an intermediate CMTX phenotype with late onset. Mutation screening of the GJB1 gene revealed a 9-bp duplication leading to the insertion of three aminoacids (Thr-Val-Phe)(More)
Mutations in the profilin 1 (PFN1) gene, encoding a protein regulating filamentous actin growth through its binding to monomeric G-actin, have been recently identified in familial amyotrophic lateral sclerosis (ALS). Functional studies performed on ALS-associated PFN1 mutants demonstrated aggregation propensity, alterations in growth cone, and cytoskeletal(More)
To elucidate the genetic architecture of amyotrophic lateral sclerosis (ALS) and find associated loci, we assembled a custom imputation reference panel from whole-genome-sequenced patients with ALS and matched controls (n = 1,861). Through imputation and mixed-model association analysis in 12,577 cases and 23,475 controls, combined with 2,579 cases and(More)
