Genes affected

SSB (HGNC:11316): (small RNA binding exonuclease protection factor La) The protein encoded by this gene is involved in diverse aspects of RNA metabolism, including binding and protecting poly(U) termini of nascent RNA polymerase III transcripts from exonuclease digestion, processing 5' and 3' ends of pre-tRNA precursors, acting as an RNA chaperone, and binding viral RNAs associated with hepatitis C virus. Autoantibodies reacting with this protein are found in the sera of patients with Sjogren syndrome and systemic lupus erythematosus. Alternative promoter usage results in two different transcript variants which encode the same protein. [provided by RefSeq, Jun 2014]

METTL5 (HGNC:25006): (methyltransferase 5, N6-adenosine) Enables S-adenosyl-L-methionine binding activity and rRNA (adenine-N6-)-methyltransferase activity. Involved in positive regulation of translation and rRNA methylation. Located in nucleus; postsynapse; and presynapse. Implicated in autosomal recessive intellectual developmental disorder-72.

Ambry Genetics

Nov 15, 2021

The c.710C>T (p.S237L) alteration is located in exon 9 (coding exon 8) of the SSB gene. This alteration results from a C to T substitution at nucleotide position 710, causing the serine (S) at amino acid position 237 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
