Genes affected
EHMT1 (HGNC:24650): (euchromatic histone lysine methyltransferase 1) The protein encoded by this gene is a histone methyltransferase that methylates the lysine-9 position of histone H3. This action marks the genomic region packaged with these methylated histones for transcriptional repression. This protein may be involved in the silencing of MYC- and E2F-responsive genes and therefore could play a role in the G0/G1 cell cycle transition. Defects in this gene are a cause of chromosome 9q subtelomeric deletion syndrome (9q-syndrome, also known as Kleefstra syndrome). Alternative splicing results in multiple transcript variants.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.91).
BP6
Variant 9-137716930-G-T is Benign according to our data. Variant chr9-137716930-G-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 462998.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.007 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.000368 (538/1460664) while in subpopulation AMR AF = 0.000671 (30/44694). AF 95% confidence interval is 0.000483. There are 1 homozygotes in GnomAdExome4. There are 268 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High AC in GnomAd4 at 47 AD gene.
