Submissions by phenotype
not specified Uncertain:1
The c.865G>A (p.E289K) alteration is located in exon 8 (coding exon 8) of the LIMS2 gene. This alteration results from a G to A substitution at nucleotide position 865, causing the glutamic acid (E) at amino acid position 289 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Autosomal recessive limb-girdle muscular dystrophy type 2W Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 287 of the LIMS2 protein (p.Glu287Lys). This variant is present in population databases (rs199761833, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with LIMS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 475551). 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) indicates that this missense variant is not expected to disrupt LIMS2 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. -
