Description

Amyotrophic lateral sclerosis (ALS) is a fatal, progressive, adult onset neurodegenerative disorder characterized by degeneration of both upper and lower motor neurons. The main symptoms include muscle fasciculations, cramps, weakness and wasting, muscle spasticity, slurred or nasal speech, and difficulties in chewing or swallowing. ALS can be sporadic or familial. The mean age of onset for sporadic and familial ALS is approximately 56 and 46 years old, respectively. Average disease duration is about three years. Death usually results from compromise of the respiratory muscles. Connective Tissue Gene Tests Amyotrophic lateral sclerosis and related disorders NGS panel consists of genes whose mutations cause or predispose ALS.

The Amyotrophic lateral sclerosis and related disorders NGS panel includes twenty-four genes: ALS2, ANG, ARHGEF28, CHCHD10, CHMP2B, ERBB4, FIG4, FUS, HNRNPA1, HNRNPA2B1, MATR3, OPTN, PFN1, SETX, SIGMAR1, SOD1, SPG11, SQSTM1, TARDBP, TBK1, TUBA4A, UBQLN2, VAPB, and VCP.
