Genes affected
UPF3B (HGNC:20439): (UPF3B regulator of nonsense mediated mRNA decay) This gene encodes a protein that is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. The encoded protein is one of two functional homologs to yeast Upf3p. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. This protein binds to the mRNA and remains bound after nuclear export, acting as a nucleocytoplasmic shuttling protein. It forms with Y14 a complex that binds specifically 20 nt upstream of exon-exon junctions. This gene is located on the long arm of chromosome X. Two splice variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.02790618).
BP6
Variant X-119838412-A-G is Benign according to our data. Variant chrX-119838412-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 212548.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000711 (8/112489) while in subpopulation AMR AF= 0.000757 (8/10572). AF 95% confidence interval is 0.000376. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
BS2
High Hemizygotes in GnomAd4 at 2 XL gene
