Genes affected

RPS7 (HGNC:10440): (ribosomal protein S7) 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 S7E family of ribosomal proteins. It is located in the cytoplasm. 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

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.12307692 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.9, offset of -29, new splice context is: gtgctcggacgcgcgctcAGggt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-3575816-G-T is Pathogenic according to our data. Variant chr2-3575816-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 372193.Status of the report is no_assertion_criteria_provided, 0 stars.
