Collection Method: clinical testing

The c.46G>T (p.G16C) alteration is located in exon 1 (coding exon 1) of the RIPPLY3 gene. This alteration results from a G to T substitution at nucleotide position 46, causing the glycine (G) at amino acid position 16 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
