Ambry Genetics

Aug 22, 2023

The c.1721G>A (p.R574H) alteration is located in exon 17 (coding exon 17) of the FCHSD1 gene. This alteration results from a G to A substitution at nucleotide position 1721, causing the arginine (R) at amino acid position 574 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
