Variant chr1-178833493-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_152663.5(RALGPS2):c.550A>G(p.Lys184Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000013 in 1,534,042 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. K184R) has been classified as Uncertain significance.

The c.550A>G (p.K184E) alteration is located in exon 8 (coding exon 7) of the RALGPS2 gene. This alteration results from a A to G substitution at nucleotide position 550, causing the lysine (K) at amino acid position 184 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
