Genes affected
KANSL1 (HGNC:24565): (KAT8 regulatory NSL complex subunit 1) This gene encodes a nuclear protein that is a subunit of two protein complexes involved with histone acetylation, the MLL1 complex and the NSL1 complex. The encoded protein has been implicated in a variety of cellular processes including enhancer regulation, cell proliferation, and mitosis. Mutations in this gene are associated with Koolen-de Vries Syndrome. [provided by RefSeq, May 2022]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.63).
BP6
Variant 17-46171847-T-C is Benign according to our data. Variant chr17-46171847-T-C is described in ClinVar as [Benign]. Clinvar id is 468405.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.735 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00156 (238/152314) while in subpopulation AFR AF= 0.00553 (230/41554). AF 95% confidence interval is 0.00495. There are 1 homozygotes in gnomad4. There are 100 alleles in male gnomad4 subpopulation. Median coverage is 35. This position pass quality control queck.
BS2
High AC in GnomAd4 at 238 AD gene.
