Ambry Genetics

Aug 22, 2023

The c.23A>G (p.D8G) alteration is located in exon 2 (coding exon 1) of the HTR1F gene. This alteration results from a A to G substitution at nucleotide position 23, causing the aspartic acid (D) at amino acid position 8 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
