Ambry Genetics RCV002433747 SCV002750810 uncertain significance Cardiovascular phenotype 2022-03-25 criteria provided, single submitter clinical testing The p.T1003I variant (also known as c.3008C>T), located in coding exon 22 of the LAMA4 gene, results from a C to T substitution at nucleotide position 3008. The threonine at codon 1003 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.
Invitae RCV002516566 SCV003455905 uncertain significance Dilated cardiomyopathy 1JJ 2022-04-03 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LAMA4-related conditions. ClinVar contains an entry for this variant (Variation ID: 191685). 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 C15"). 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. This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 1003 of the LAMA4 protein (p.Thr1003Ile).
