Ambry Genetics

Apr 17, 2023

The c.192C>A (p.S64R) alteration is located in exon 2 (coding exon 2) of the SDF2L1 gene. This alteration results from a C to A substitution at nucleotide position 192, causing the serine (S) at amino acid position 64 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
