Variant 17-45396997-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001282290.2(ARHGAP27):c.1870G>C(p.Glu624Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000689 in 1,452,224 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E624K) has been classified as Uncertain significance.

Genes affected

ARHGAP27 (HGNC:31813): (Rho GTPase activating protein 27) This gene encodes a member of a large family of proteins that activate Rho-type guanosine triphosphate (GTP) metabolizing enzymes. The encoded protein may pay a role in clathrin-mediated endocytosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.847G>C (p.E283Q) alteration is located in exon 11 (coding exon 10) of the ARHGAP27 gene. This alteration results from a G to C substitution at nucleotide position 847, causing the glutamic acid (E) at amino acid position 283 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
