Genes affected

MUC16 (HGNC:15582): (mucin 16, cell surface associated) This gene encodes a protein that is a member of the mucin family. Mucins are high molecular weight, O-glycosylated proteins that play an important role in forming a protective mucous barrier, and are found on the apical surfaces of the epithelia. The encoded protein is a membrane-tethered mucin that contains an extracellular domain at its amino terminus, a large tandem repeat domain, and a transmembrane domain with a short cytoplasmic domain. The amino terminus is highly glycosylated, while the repeat region contains 156 amino acid repeats unit that are rich in serines, threonines, and prolines. Interspersed within the repeats are Sea urchin sperm protein Enterokinase and Agrin (SEA) modules, leucine-rich repeats and ankyrin (ANK) repeats. These regions together form the ectodomain, and there is a potential cleavage site found near an SEA module close to the transmembrane domain. This protein is thought to play a role in forming a barrier, protecting epithelial cells from pathogens. Products of this gene have been used as a marker for different cancers, with higher expression levels associated with poorer outcomes. [provided by RefSeq, May 2017]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0039216876).
• BP6: Variant 19-8851713-G-A is Benign according to our data. Variant chr19-8851713-G-A is described in ClinVar as [Benign]. Clinvar id is 3056717.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0273 (4054/148482) while in subpopulation NFE AF= 0.0437 (2931/67058). AF 95% confidence interval is 0.0424. There are 71 homozygotes in gnomad4. There are 1897 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 71 AR gene
