Development and validation of a targeted NGS panel for diagnosing familial hemiplegic migraine (FHM), episodic ataxia type 2 (EA2), CADASIL, and migraine with aura. In 149 patients across 4 cohorts (55 FHM, 44 CADASIL, 31 EA2, 19 migraine families), the panel identified novel and known mutations in genes CACNA1A, ATP1A2, SCN1A, and NOTCH3, increasing mutation detection rate from 7.7% to 28.5%. Notably, ATP1A2 and NOTCH3 mutations were identified in typical migraine with aura families for the first time, demonstrating aetiological overlap with FHM.
About HTR2B
This gene encodes one of the several different receptors for 5-hydroxytryptamine (serotonin) that belongs to the G-protein coupled receptor 1 family. Serotonin is a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. Serotonin receptors mediate many of the central and peripheral physiologic functions of serotonin, including regulation of cardiovascular functions and impulsive behavior. Population and family-based analyses of a minor allele (glutamine-to-stop substitution, designated Q20*) which blocks expression of this protein, and knockout studies in mice, suggest a role for this gene in impulsivity. However, other factors, such as elevated testosterone levels, may also be involved. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2016]
