Genes affected
CHD7 (HGNC:20626): (chromodomain helicase DNA binding protein 7) This gene encodes a protein that contains several helicase family domains. Mutations in this gene have been found in some patients with the CHARGE syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.82).
BP6
Variant 8-60865600-G-A is Benign according to our data. Variant chr8-60865600-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 158323.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.385 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0000985 (15/152308) while in subpopulation AMR AF = 0.000327 (5/15298). AF 95% confidence interval is 0.000129. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
