Quick test description:

Testing for familial AD variants of SPAST gene (SPG4) and REEP1 gene (SPG31) using the NGS method.

Test details:

Hereditary spastic paraparesis is a heterogeneous group of diseases that can be mediated by disorders in many genes, only a fraction of which are known. The testing for all 17 coding exons of the SPAST (SPG4) gene (NM_014946.3; ENST00000615843.4) and 7 coding exons of the REEP1 (SPG31) gene (NM_022912; ENST00000165698.9) is performed by Massively Parallel Sequencing (NGS) on the Illumina platform (NextSeq) using the CarrierTest NGS panel. The obtained data are analysed according to our own bioinformatic evaluation, which includes alignment to the GRCh38 genome reference sequence, variant calling, annotation with the current version of Ensembl and filtering of target variants according to the current version of the panel. Each of the above steps is complemented by quality control.
