ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.25786164 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.3, offset of 6, new splice context is: gattcctgtggcaactgcAGgga. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
BP6
Variant 19-17226993-G-A is Benign according to our data. Variant chr19-17226993-G-A is described in ClinVar as [Benign]. Clinvar id is 717086.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00649 (988/152256) while in subpopulation AFR AF= 0.0223 (925/41550). AF 95% confidence interval is 0.0211. There are 14 homozygotes in gnomad4. There are 459 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 14 AR gene
