Variant 21-43793402-A-G details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_003683.6(RRP1):c.358A>G(p.Met120Val) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,460,244 control chromosomes in the GnomAD database, with no homozygous occurrence. 14/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

RRP1 (HGNC:18785): (ribosomal RNA processing 1) The protein encoded by this gene is the putative homolog of the yeast ribosomal RNA processing protein RRP1. The encoded protein is involved in the late stages of nucleologenesis at the end of mitosis, and may be required for the generation of 28S rRNA. [provided by RefSeq, Jul 2008]

The c.358A>G (p.M120V) alteration is located in exon 4 (coding exon 4) of the RRP1 gene. This alteration results from a A to G substitution at nucleotide position 358, causing the methionine (M) at amino acid position 120 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
