Sep 08, 2024

The c.85C>G (p.R29G) alteration is located in exon 1 (coding exon 1) of the TICRR gene. This alteration results from a C to G substitution at nucleotide position 85, causing the arginine (R) at amino acid position 29 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
