Ambry Genetics

Sep 30, 2021

The c.14C>G (p.T5R) alteration is located in exon 1 (coding exon 1) of the ZDHHC20 gene. This alteration results from a C to G substitution at nucleotide position 14, causing the threonine (T) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
