Variant 10-90896315-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_006413.5(RPP30):c.620G>C(p.Gly207Ala) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000204 in 1,613,830 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. 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. G207D) has been classified as Uncertain significance.

Ambry Genetics

Sep 27, 2022

The c.620G>C (p.G207A) alteration is located in exon 10 (coding exon 10) of the RPP30 gene. This alteration results from a G to C substitution at nucleotide position 620, causing the glycine (G) at amino acid position 207 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
