| Quest Diagnostics Nichols Institute San Juan Capistrano | RCV000759072 | SCV000888158 | uncertain significance | not provided | 2022-10-26 | criteria provided, single submitter | clinical testing | It has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). In the published literature, the variant has been reported in an individual with erythrocytosis and in an individual with normal hematologic findings whose Hb F was high (4.7%) and Hb A2 was normal (2.8%) (PMID: 31388287 (2019)). Functional studies have shown that the Hb Ty Gard variant has a normal Hb Bohr effect, normal cooperativity, increased oxygen affinity, and is relatively stable (PMID: 639985 (1978)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant. |
