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]

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Mar 13, 2017 | The c.-19+1 G>C variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. Several in-silico splice prediction models predict that c.-19+1 G>C destroys the canonical splice donor site of exon 1; however, exon 1 is non-coding. In the absence of RNA/functional studies, the actual effect of this sequence change in this individual is unknown. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. - |
