Collection Method: clinical testing

The c.622C>G (p.P208A) alteration is located in exon 6 (coding exon 6) of the SIDT2 gene. This alteration results from a C to G substitution at nucleotide position 622, causing the proline (P) at amino acid position 208 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
