Genes affected

TOPORS (HGNC:21653): (TOP1 binding arginine/serine rich protein, E3 ubiquitin ligase) This gene encodes a nuclear protein which is serine and arginine rich, and contains a RING-type zinc finger domain. It is highly expressed in the testis, and functions as an ubiquitin-protein E3 ligase. Mutations in this gene are associated with retinitis pigmentosa type 31. Alternatively spliced transcript variants, encoding different isoforms, have been observed for this locus. [provided by RefSeq, Sep 2010]

ENSG00000288684 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS1: Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000105 (2/18972) while in subpopulation NFE AF= 0.000187 (2/10696). AF 95% confidence interval is 0.0000328. There are 0 homozygotes in gnomad4_exome. There are 1 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
