NM_181335.3:c.88C>T

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_181335.3(ARHGAP8):​c.88C>T​(p.Arg30Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000026 in 1,614,134 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. 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. R30G) has been classified as Uncertain significance.

Genes affected
ARHGAP8 (HGNC:677): (Rho GTPase activating protein 8) This gene encodes a member of the RHOGAP family. GAP (GTPase-activating) family proteins participate in signaling pathways that regulate cell processes involved in cytoskeletal changes. GAP proteins alternate between an active (GTP-bound) and inactive (GDP-bound) state based on the GTP:GDP ratio in the cell. This family member is a multidomain protein that functions to promote Erk activation and cell motility. Alternative splicing results in multiple transcript variants. Read-through transcripts from the upstream proline rich 5, renal (PRR5) gene into this gene also exist, which led to the original description of PRR5 and ARHGAP8 being a single gene. [provided by RefSeq, Nov 2010]
PRR5-ARHGAP8 (HGNC:34512): (PRR5-ARHGAP8 readthrough) The PRR5-ARHGAP8 mRNA is an infrequent but naturally occurring read-through transcript of the neighboring proline rich 5, renal (PRR5) and Rho GTPase activating protein 8 (ARHGAP8) genes. The resulting fusion protein contains sequence identity with each individual gene product, and it includes domains characteristic of a RhoGAP protein. The significance of this read-through transcript and the function of its protein product have not yet been determined. [provided by RefSeq, Nov 2010]
