Ambry Genetics

Oct 03, 2022

The c.698C>G (p.A233G) alteration is located in exon 2 (coding exon 2) of the SP5 gene. This alteration results from a C to G substitution at nucleotide position 698, causing the alanine (A) at amino acid position 233 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
