Invitae | RCV000641082 | SCV000762700 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2F | 2019-04-18 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine with isoleucine at codon 102 of the HSPB1 protein (p.Asn102Ile). The asparagine residue is highly conserved and there is a large physicochemical difference between asparagine and isoleucine. While this variant is not present in population databases, the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with HSPB1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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. |

RCV001162475 | SCV001324428 | uncertain significance | Distal hereditary motor neuronopathy type 2B | 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. |
