Genes affected
HTR1A (HGNC:5286): (5-hydroxytryptamine receptor 1A) This gene encodes a G protein-coupled receptor for 5-hydroxytryptamine (serotonin), and belongs to the 5-hydroxytryptamine receptor subfamily. Serotonin has been implicated in a number of physiologic processes and pathologic conditions. Inactivation of this gene in mice results in behavior consistent with an increased anxiety and stress response. Mutation in the promoter of this gene has been associated with menstrual cycle-dependent periodic fevers. [provided by RefSeq, Jun 2012]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 22, 2022 | The c.416C>T (p.T139M) alteration is located in exon 1 (coding exon 1) of the HTR1A gene. This alteration results from a C to T substitution at nucleotide position 416, causing the threonine (T) at amino acid position 139 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
