Genes affected

SCN11A (HGNC:10583): (sodium voltage-gated channel alpha subunit 11) Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit with 24 transmembrane domains and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel alpha subunit gene family, and is highly expressed in nociceptive neurons of dorsal root ganglia and trigeminal ganglia. It mediates brain-derived neurotrophic factor-evoked membrane depolarization and is a major effector of peripheral inflammatory pain hypersensitivity. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy type VII and familial episodic pain syndrome-3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2017]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.4).

BP6

Variant 3-38896950-G-A is Benign according to our data. Variant chr3-38896950-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 474702.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.24 with no splicing effect.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000184 (269/1461866) while in subpopulation MID AF = 0.000173 (1/5768). AF 95% confidence interval is 0.0000597. There are 2 homozygotes in GnomAdExome4. There are 129 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.

BS2

High AC in GnomAd4 at 25 AD gene.
