Genes affected

HTR7 (HGNC:5302): (5-hydroxytryptamine receptor 7) The neurotransmitter, serotonin, is thought to play a role in various cognitive and behavioral functions. The serotonin receptor encoded by this gene belongs to the superfamily of G protein-coupled receptors and the gene is a candidate locus for involvement in autistic disorder and other neuropsychiatric disorders. Three splice variants have been identified which encode proteins that differ in the length of their carboxy terminal ends. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 27, 2023

The c.997G>A (p.V333I) alteration is located in exon 2 (coding exon 2) of the HTR7 gene. This alteration results from a G to A substitution at nucleotide position 997, causing the valine (V) at amino acid position 333 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
