Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BS1

The NM_001349253.2(SCN11A):c.4064G>C(p.Cys1355Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000316 in 1,581,138 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C1355Y) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000028 (4/1429026) while in subpopulation AMR AF = 0.000105 (4/37956). AF 95% confidence interval is 0.0000356. There are 0 homozygotes in GnomAdExome4. There are 2 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.
