Illumina Laboratory Services, Illumina RCV000327621 SCV000452304 uncertain significance Pyridoxine-dependent epilepsy 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Ambry Genetics RCV002392780 SCV002697800 uncertain significance Inborn genetic diseases 2018-07-19 criteria provided, single submitter clinical testing The p.R469H variant (also known as c.1406G>A), located in coding exon 15 of the ALDH7A1 gene, results from a G to A substitution at nucleotide position 1406. The arginine at codon 469 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
