Invitae RCV000795381 SCV000934844 uncertain significance Hereditary sensory and autonomic neuropathy type IIA; Generalized epilepsy with febrile seizures plus, type 7 2018-08-11 criteria provided, single submitter clinical testing This sequence change replaces lysine with asparagine at codon 655 of the SCN9A protein (p.Lys655Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant is present in population databases (rs369989247, ExAC 0.003%). This variant has not been reported in the literature in individuals with SCN9A-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C35". The asparagine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Illumina Clinical Services Laboratory,Illumina RCV001132095 SCV001291749 uncertain significance Primary erythromelalgia 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina RCV001132096 SCV001291750 uncertain significance Indifference to pain, congenital, autosomal recessive 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina RCV001133027 SCV001292713 uncertain significance Paroxysmal extreme pain disorder 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
