Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.503G>T (p.C168F) alteration is located in exon 1 (coding exon 1) of the HTR1D gene. This alteration results from a G to T substitution at nucleotide position 503, causing the cysteine (C) at amino acid position 168 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
