RCV000150402 | SCV000197579 | uncertain significance | not specified | 2014-04-12 | criteria provided, single submitter | clinical testing | The Ile891Thr variant in DIAPH1 has not been previously reported in individuals with hearing loss and was absent from large population studies. Computational p rediction tools and conservation analyses do not provide strong support for or a gainst an impact to the protein. In summary, additional information is needed to fully assess its clinical significance. |

RCV000269313 | SCV000453365 | uncertain significance | Autosomal dominant nonsyndromic hearing loss 1 | 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. |
Invitae | RCV003764908 | SCV004568430 | uncertain significance | Autosomal dominant nonsyndromic hearing loss 1; Progressive microcephaly-seizures-cortical blindness-developmental delay syndrome | 2022-12-25 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 163071). This variant has not been reported in the literature in individuals affected with DIAPH1-related conditions. This variant is present in population databases (rs727502961, gnomAD 0.0009%). This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 891 of the DIAPH1 protein (p.Ile891Thr). |
