Ambry Genetics

Dec 06, 2022

The c.634T>C (p.F212L) alteration is located in exon 8 (coding exon 8) of the ZDHHC20 gene. This alteration results from a T to C substitution at nucleotide position 634, causing the phenylalanine (F) at amino acid position 212 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
