Mutation analysis of the SPG4 gene in Italian patients with pure and complicated forms of spastic paraplegia
2010
Mutations in the SPG4 gene are the most common causes of hereditary spastic paraplegia (HSP) accounting for up to 40% of autosomal dominant (AD) forms and 12-18% of sporadic cases. The phenotype associated with HSP due to mutations in the SPG4 gene tends to be pure. There is increasing evidence, however, of patients with complicated forms of spastic paraplegia in which SPG4 mutations were identified. A cohort of 38 unrelated Italian patients with spastic paraplegia, of which 24 had a clear dominant inheritance and 14 were apparently sporadic, were screened for mutations in the SPG4 gene.We identified 11 different mutations, six of which were novel (p.Glu143GlyfsX8, p.Tyr415X, p.Asp548Asn, c…
Analisi MLPA del gene CREB-binding protein (CREBBP) in un paziente con la sindrome di Rubinstein Taybi
2012
La sindrome di Rubinstein-Taybi è una rara malattia congenita autosomica dominante caratterizzata da ritardo della crescita postnatale, ritardo dello sviluppo psicomotorio, anomalie scheletriche, peculiare morfologia facciale ed un aumento del rischio oncogeno. La prevalenza alla nascita è 1 su 125.000 nati vivi. La malattia può essere associata a mutazioni nel gene che codifica per la proteina CREB-binding localizzato nella regione cromosomica 16p13.3. Recenti studi hanno dimostrato che pazienti con quoziente intellettivo basso e tratti autistici possono avere grandi delezioni. Sulla base di queste osservazioni, abbiamo usato la Multiplex Ligation-dependent Probe Amplification (MLPA) per r…
Genetic profile and immunohistochemical study of clear cell renal carcinoma: Pathological-anatomical correlation and prognosis.
2021
Abstract Introduction Renal cell carcinoma (RCC) accounts for 2–3% of all tumors being the most frequent solid lesion in the kidney. Objective To determine what genetic alterations and immunohistochemical (IHC) of clear cell renal carcinoma (ccRCC) are associated with prognosis and tumor aggressiveness. Patients and Methods Experimental analytical study with 57 patients who underwent radical and partial nephrectomy between 2005 and 2011, all with diagnosis of ccRCC and minimum post-operative follow-up of 36 months. The pathological study included IHC determination of biomarkers associated (CAIX, CAM 5.2, CD10, c-erbB-2, EGFR, HIF-1a, Ki67, MDM2, PAX-2 y 8, p53, survivin and VEGFR 1 and 2). …
