Genes affected

RTCA (HGNC:17981): (RNA 3'-terminal phosphate cyclase) This gene encodes a member of the RNA 3'-phosphate cyclase family. The encoded protein plays a role in RNA metabolism by catalyzing the ATP-dependent conversion of the 3'-phosphate of RNA substrates to a 2',3'-cyclic phosphodiester. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2012]

Ambry Genetics

Jun 16, 2023

The c.106G>A (p.V36M) alteration is located in exon 2 (coding exon 2) of the RTCA gene. This alteration results from a G to A substitution at nucleotide position 106, causing the valine (V) at amino acid position 36 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
