Genes affected
SRCAP (HGNC:16974): (Snf2 related CREBBP activator protein) This gene encodes the core catalytic component of the multiprotein chromatin-remodeling SRCAP complex. The encoded protein is an ATPase that is necessary for the incorporation of the histone variant H2A.Z into nucleosomes. It can function as a transcriptional activator in Notch-mediated, CREB-mediated and steroid receptor-mediated transcription. Mutations in this gene cause Floating-Harbor syndrome, a rare disorder characterized by short stature, language deficits and dysmorphic facial features. [provided by RefSeq, Feb 2012]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 16-30704141-C-T is Benign according to our data. Variant chr16-30704141-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 160032.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.189 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00181 (275/152296) while in subpopulation NFE AF = 0.003 (204/68026). AF 95% confidence interval is 0.00266. There are 1 homozygotes in GnomAd4. There are 126 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 275 AD gene.
