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

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5).
• BP6: Variant 5-88761275-G-A is Benign according to our data. Variant chr5-88761275-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 138202.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000903 (132/1461690) while in subpopulation NFE AF = 0.000108 (120/1111852). AF 95% confidence interval is 0.000092. There are 0 homozygotes in GnomAdExome4. There are 64 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 6 AD gene.
