Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4_Moderate BP6_Moderate BP7 BS1

The NM_001022.4(RPS19):c.75C>G(p.Ser25=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000031 in 1,613,482 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 Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. S25S) has been classified as Likely benign.

Genes affected

RPS19 (HGNC:10402): (ribosomal protein S19) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit. The protein belongs to the S19E family of ribosomal proteins. It is located in the cytoplasm. Mutations in this gene cause Diamond-Blackfan anemia (DBA), a constitutional erythroblastopenia characterized by absent or decreased erythroid precursors, in a subset of patients. This suggests a possible extra-ribosomal function for this gene in erythropoietic differentiation and proliferation, in addition to its ribosomal function. Higher expression levels of this gene in some primary colon carcinomas compared to matched normal colon tissues has been observed. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).
• BP6: Variant 19-41861115-C-G is Benign according to our data. Variant chr19-41861115-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 704181.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.081 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000322 (47/1461332) while in subpopulation NFE AF= 0.0000405 (45/1111704). AF 95% confidence interval is 0.0000309. There are 0 homozygotes in gnomad4_exome. There are 26 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
