Ambry Genetics

Oct 20, 2021

The c.277G>T (p.D93Y) alteration is located in exon 5 (coding exon 4) of the SYCP1 gene. This alteration results from a G to T substitution at nucleotide position 277, causing the aspartic acid (D) at amino acid position 93 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
