Genes affected

MED12L (HGNC:16050): (mediator complex subunit 12L) The protein encoded by this gene is part of the Mediator complex, which is involved in transcriptional coactivation of nearly all RNA polymerase II-dependent genes. The Mediator complex links gene-specific transcriptional activators with the basal transcription machinery. [provided by RefSeq, May 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 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), MED12L. . Gene score misZ 3.132 (greater than the threshold 3.09). Trascript score misZ 3.991 (greater than threshold 3.09). GenCC has associacion of gene with Nizon-Isidor syndrome, autosomal dominant non-syndromic intellectual disability.

The c.61C>T (p.P21S) alteration is located in exon 1 (coding exon 1) of the MED12L gene. This alteration results from a C to T substitution at nucleotide position 61, causing the proline (P) at amino acid position 21 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
