ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
BP6
Variant 16-89903-C-G is Benign according to our data. Variant chr16-89903-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 542800.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000187 (26/1392886) while in subpopulation AMR AF= 0.000721 (25/34686). AF 95% confidence interval is 0.0005. There are 0 homozygotes in gnomad4_exome. There are 16 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 26 AD gene.
