Submissions by phenotype
Myopathy, lactic acidosis, and sideroblastic anemia 2 Pathogenic:1
Likely pathogenicity based on finding it once in our laboratory in trans with a pathogenic variant [D121fs] in a 39-year-old male with sideroblastic or congenital dyserythropoietic anemia, dyserythropoietic bone marrow with macrocytic anemia, angioid streaks on retina, possible pseudoxanthoma elasticum, fatigue, chronic joint pain, sister with macrocytic anemia and similar bone marrow phenotype [not tested]. Variant likely pathogenic in recessive state; heterozygotes would be carriers. -
not provided Pathogenic:1
This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 251 of the YARS2 protein (p.Ile251Val). This variant is present in population databases (rs372098364, gnomAD 0.01%). This missense change has been observed in individual(s) with YARS2-related conditions (PMID: 26944241, 33144682). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 209209). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on YARS2 protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
