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 Benign. Variant got -11 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.45).
BP6
Variant 5-88751861-G-A is Benign according to our data. Variant chr5-88751861-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 94061.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=2}.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000198 (29/1461536) while in subpopulation AMR AF= 0.000447 (20/44722). AF 95% confidence interval is 0.000296. There are 0 homozygotes in gnomad4_exome. There are 10 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 29 AD gene.
