Genes affected
HTR3E (HGNC:24005): (5-hydroxytryptamine receptor 3E) This locus encodes a 5-hydroxytryptamine (serotonin) receptor subunit. The encoded protein, subunit E, may play a role in neurotransmission in myenteric neurons. Genes encoding subunits C, D and E form a cluster on chromosome 3. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Feb 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.627G>A (p.M209I) alteration is located in exon 5 (coding exon 5) of the HTR3E gene. This alteration results from a G to A substitution at nucleotide position 627, causing the methionine (M) at amino acid position 209 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
