The c.229C>G (p.R77G) alteration is located in exon 1 (coding exon 1) of the TGFBR3L gene. This alteration results from a C to G substitution at nucleotide position 229, causing the arginine (R) at amino acid position 77 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
