Genes affected
MEF2C (HGNC:6996): (myocyte enhancer factor 2C) This locus encodes a member of the MADS box transcription enhancer factor 2 (MEF2) family of proteins, which play a role in myogenesis. The encoded protein, MEF2 polypeptide C, has both trans-activating and DNA binding activities. This protein may play a role in maintaining the differentiated state of muscle cells. Mutations and deletions at this locus have been associated with severe cognitive disability, stereotypic movements, epilepsy, and cerebral malformation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2010]
MEF2C-AS2 (HGNC:53115): (MEF2C antisense RNA 2)

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 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), MEF2C. . Gene score misZ 3.9523 (greater than the threshold 3.09). Trascript score misZ 4.8218 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 20, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.30317467).
BP6
Variant 5-88722641-A-G is Benign according to our data. Variant chr5-88722641-A-G is described in ClinVar as [Benign]. Clinvar id is 652831.Status of the report is criteria_provided_single_submitter, 1 stars.
