not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.866G>A (p.R289Q) alteration is located in exon 2 (coding exon 1) of the HTR1F gene. This alteration results from a G to A substitution at nucleotide position 866, causing the arginine (R) at amino acid position 289 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
