Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide, deletion-insertion, and copy number variants in 56 genes associated with focal segmental glomerulosclerosis and nephrotic syndrome: ACTN4, ALG1, ANLN, APOL1 [Chr22(GRCh37):g.36661895-36661916 and g.36662023-36662062 only], ARHGAP24, ARHGDIA, CD2AP, CLCN5, COL4A3, COL4A4, COL4A5, COQ2, COQ6, COQ8B, CRB2, CUBN, DGKE, EMP2, FAN1, FAT1, FN1, INF2, ITGA3, ITGB4, KANK2, LAMA5, LAMB2, LMX1B, MAGI2, MYH9, MYO1E, NPHS1, NPHS2, NUP107, NUP133, NUP160, NUP205, NUP85, NUP93, OCRL, PAX2, PDSS2, PLCE1, PLCG2, PMM2, PODXL, PTPRO, SCARB2, SGPL1, SMARCAL1, TBC1D8B, TRPC6, TTC21B, WDR73, WT1, ZMPSTE24. See Targeted Genes and Methodology Details for Focal Segmental Glomerulosclerosis and Nephrotic Syndrome Gene Panel in Method Description for additional details.
Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for focal segmental glomerulosclerosis or nephrotic syndrome.
