Ambry Genetics

Apr 04, 2023

The c.814G>A (p.A272T) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a G to A substitution at nucleotide position 814, causing the alanine (A) at amino acid position 272 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
