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]

The c.1069C>T (p.R357C) alteration is located in exon 9 (coding exon 9) of the RPL3L gene. This alteration results from a C to T substitution at nucleotide position 1069, causing the arginine (R) at amino acid position 357 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
