• chr5-73852656-G-C
• rs2973566
• NM_001177693.2:c.1754G>C

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001177693.2(ARHGEF28):​c.1754G>C​(p.Arg585Thr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R585K) has been classified as Benign.

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: AD, AR Classification: MODERATE Submitted by: Genomics England PanelApp

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
