RCV000311019 | SCV000410858 | likely benign | Congenital dyserythropoietic anemia type 4 | 2018-01-13 | 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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. |

RCV002292526 | SCV003251521 | uncertain significance | not provided | 2023-12-02 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 87 of the KLF1 protein (p.Pro87Ala). This variant is present in population databases (rs752204035, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with KLF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 328323). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt KLF1 protein function with a negative predictive value of 80%. 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. |
