Ambry Genetics

Dec 13, 2022

The c.644C>G (p.P215R) alteration is located in exon 3 (coding exon 3) of the SPERT gene. This alteration results from a C to G substitution at nucleotide position 644, causing the proline (P) at amino acid position 215 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
