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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2023The c.788C>A (p.A263D) alteration is located in exon 9 (coding exon 9) of the RTCA gene. This alteration results from a C to A substitution at nucleotide position 788, causing the alanine (A) at amino acid position 263 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
