Genetic factors affecting course of selected forms of nephrotic syndrome
Šafaříková, Markéta ; Štekrová, Jitka (advisor) ; Král, Jiří (referee)
Nephrotic syndrome (NS) is characterized by proteinuria, hypalbuminemia and edemas. It occurs during first and second glomerulopathies. This disease can be divided into two groups: primary (idiopathic) and secondary. The heredity of the familial nephrotic syndrome is autosomal dominant and autosomal recessive. There are four most important genes that condition the formation of hereditary nephrotic syndrome in adult patienst. These genes are ACTN4, CD2AP, NPHS2 and TRPC6. The gene ACTN4, which encodes protein α-actinin 4, is responsible for the autosomal dominant form of focal segmental glomerulosclerosis (FSGS). FSGS is included in first glomerulopathies. α-Actinin 4 was also researched for some types of carcinomas. There was performed the mutational analysis of the gene ACTN4 on the set of 48 patients with nephrotic syndrome in this diploma thesis. High resolution melting (HRM) analysis and sequencing selected samples were used during this mutation detection. During this process many published and unpublished SNPs and one unpublished candidate mutation that could have causal associations with FSGS were found.

Genetic factors of progression of selected forms of chronicnephropathies.
Šafaříková, Markéta ; Reiterová, Jana (advisor) ; Brdička, Radim (referee) ; Gaillyová, Renata (referee)
Nephrotic syndrome is characterized by proteinuria, hypoproteinemia, edemas and hyperlipidemia. It occurs in primary (e.g. focal segmental glomerulosclerosis, FSGS or minimal change disease, MCD) and in secondary glomerulopathies (e.g. kidney amyloidosis). In primary forms, great attention is paid to the potential genetic background of the disease and due to new molecular genetic methods genes, whose mutations cause different nephropathies (e.g. ACTN4 or INF2) were identified. The aims of presented doctoral thesis were following. Firstly, to continue the mutational analysis of ACTN4 that was described in the author's diploma thesis in other glomerulopathies. Secondly, to implement the mutational analysis of INF2 and subsequently analyse this gene in patients with FSGS/MCD and in patients from special group characterized by positive family history for end stage renal disease (ESRD) in combination with advanced chronic kidney disease (CKD) or already developed ESRD at the time of diagnosis. Thirdly, mutational analysis of NPHS2 and TRPC6 (methods implemented in laboratory earlier) in selected patients from the special group. Finally, expression analyses of genes important for podocyte function or connected with human immune system. This part also verifies the applicability of NPHS2/SYNPO expression...
