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

Mar 01, 2023

The c.6G>A (p.M2I) alteration is located in exon 1 (coding exon 1) of the HTR7 gene. This alteration results from a G to A substitution at nucleotide position 6, causing the methionine (M) at amino acid position 2 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
