Ambry Genetics

Dec 26, 2023

The c.220G>T (p.D74Y) alteration is located in exon 1 (coding exon 1) of the FAM110C gene. This alteration results from a G to T substitution at nucleotide position 220, causing the aspartic acid (D) at amino acid position 74 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
