Genes affected

ARHGEF28 (HGNC:30322): (Rho guanine nucleotide exchange factor 28) This gene encodes a member of the Rho guanine nucleotide exchange factor family. The encoded protein interacts with low molecular weight neurofilament mRNA and may be involved in the formation of amyotrophic lateral sclerosis neurofilament aggregates. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Apr 2010]

Collection Method: clinical testing

The c.146G>A (p.R49H) alteration is located in exon 3 (coding exon 2) of the ARHGEF28 gene. This alteration results from a G to A substitution at nucleotide position 146, causing the arginine (R) at amino acid position 49 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
