Genes affected

MED13L (HGNC:22962): (mediator complex subunit 13L) The protein encoded by this gene is a subunit of the Mediator complex, a large complex of proteins that functions as a transcriptional coactivator for most RNA polymerase II-transcribed genes. The encoded protein is involved in early development of the heart and brain. Defects in this gene are a cause of transposition of the great arteries, dextro-looped (DTGA).[provided by RefSeq, Jul 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MED13L. . Gene score misZ 3.691 (greater than the threshold 3.09). Trascript score misZ 6.2821 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, syndromic intellectual disability, congenital heart disease, cardiac anomalies - developmental delay - facial dysmorphism syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.828

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 2190 of the MED13L protein (p.Ser2190Cys). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with MED13L-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MED13L protein function. 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. -
