Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The ENST00000230538.12(LAMA4):c.4646A>T(p.Asn1549Ile) variant causes a missense change. The variant allele was found at a frequency of 0.0000149 in 1,613,778 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N1549S) has been classified as Likely benign.

Dilated cardiomyopathy 1JJ Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 29, 2023 | This variant is present in population databases (rs12110554, gnomAD 0.007%). This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 1542 of the LAMA4 protein (p.Asn1542Ile). 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: 1018765). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. - |
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 21, 2022 | The p.N1542I variant (also known as c.4625A>T), located in coding exon 32 of the LAMA4 gene, results from an A to T substitution at nucleotide position 4625. The asparagine at codon 1542 is replaced by isoleucine, an amino acid with dissimilar 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. - |
LAMA4-related disorder Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 26, 2024 | The LAMA4 c.4625A>T variant is predicted to result in the amino acid substitution p.Asn1542Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
