Genes affected

RPS2 (HGNC:10404): (ribosomal protein S2) 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 S5P family of ribosomal proteins. It is located in the cytoplasm. This gene shares sequence similarity with mouse LLRep3. It is co-transcribed with the small nucleolar RNA gene U64, which is located in its third intron. 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]

NDUFB10 (HGNC:7696): (NADH:ubiquinone oxidoreductase subunit B10) Involved in mitochondrial respiratory chain complex I assembly. Located in mitochondrial inner membrane. Part of mitochondrial respiratory chain complex I. Implicated in nuclear type mitochondrial complex I deficiency 35. [provided by Alliance of Genome Resources, Apr 2022]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.871G>A (p.A291T) alteration is located in exon 7 (coding exon 6) of the RPS2 gene. This alteration results from a G to A substitution at nucleotide position 871, causing the alanine (A) at amino acid position 291 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
