Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2022The c.736G>A (p.V246I) 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 736, causing the valine (V) at amino acid position 246 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
