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]

The c.236C>T (p.T79I) alteration is located in exon 1 (coding exon 1) of the HTR3E gene. This alteration results from a C to T substitution at nucleotide position 236, causing the threonine (T) at amino acid position 79 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
