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]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0014189482).
• BP6: Variant 5-73852656-G-A is Benign according to our data. Variant chr5-73852656-G-A is described in ClinVar as [Benign]. Clinvar id is 257360.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-73852656-G-A is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.285 is higher than 0.05.
