Collection Method: clinical testing

The c.440C>A (p.P147H) alteration is located in exon 5 (coding exon 5) of the RCSD1 gene. This alteration results from a C to A substitution at nucleotide position 440, causing the proline (P) at amino acid position 147 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
