Sep 16, 2021

The c.149C>A (p.P50H) alteration is located in exon 2 (coding exon 2) of the RWDD3 gene. This alteration results from a C to A substitution at nucleotide position 149, causing the proline (P) at amino acid position 50 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
