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]

ARHGEF28 Gene-Disease associations (from GenCC):

• amyotrophic lateral sclerosis

  Inheritance: AR, AD, SD Classification: MODERATE, LIMITED Submitted by: Genomics England PanelApp, ClinGen

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 5-73749654-A-G is Benign according to our data. Variant chr5-73749654-A-G is described in ClinVar as Benign. ClinVar VariationId is 1234878.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0749 is higher than 0.05.
