Ambry Genetics

Oct 06, 2021

The c.1077G>C (p.E359D) alteration is located in exon 9 (coding exon 8) of the PACSIN1 gene. This alteration results from a G to C substitution at nucleotide position 1077, causing the glutamic acid (E) at amino acid position 359 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
