Genes affected

RPL6 (HGNC:10362): (ribosomal protein L6) This gene encodes a protein component of the 60S ribosomal subunit. This protein can bind specifically to domain C of the tax-responsive enhancer element of human T-cell leukemia virus type 1, and may participate in tax-mediated transactivation of transcription. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed throughout the genome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11001763).

Collection Method: clinical testing

The c.506C>T (p.A169V) alteration is located in exon 5 (coding exon 4) of the RPL6 gene. This alteration results from a C to T substitution at nucleotide position 506, causing the alanine (A) at amino acid position 169 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
