Genes affected

RPL3L (HGNC:10351): (ribosomal protein L3 like) This gene encodes a protein that shares sequence similarity with ribosomal protein L3. The protein belongs to the L3P family of ribosomal proteins. Unlike the ubiquitous expression of ribosomal protein genes, this gene has a tissue-specific pattern of expression, with the highest levels of expression in skeletal muscle and heart. It is not currently known whether the encoded protein is a functional ribosomal protein or whether it has evolved a function that is independent of the ribosome. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.918C>A (p.S306R) alteration is located in exon 7 (coding exon 7) of the RPL3L gene. This alteration results from a C to A substitution at nucleotide position 918, causing the serine (S) at amino acid position 306 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
