Ambry Genetics

Aug 13, 2021

The c.1024C>G (p.R342G) alteration is located in exon 7 (coding exon 6) of the SPSB3 gene. This alteration results from a C to G substitution at nucleotide position 1024, causing the arginine (R) at amino acid position 342 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
