Jun 03, 2024

The c.1430T>G (p.L477W) alteration is located in exon 10 (coding exon 10) of the RHCG gene. This alteration results from a T to G substitution at nucleotide position 1430, causing the leucine (L) at amino acid position 477 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
