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]

HTR3E-AS1 (HGNC:41032): (HTR3E antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=6.6547994E-7).
• BP6: Variant 3-184100628-G-A is Benign according to our data. Variant chr3-184100628-G-A is described in ClinVar as [Benign]. Clinvar id is 1242214.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.87 is higher than 0.05.
