Genes affected

MUC19 (HGNC:14362): (mucin 19, oligomeric) This gene encodes a member of the gel-forming mucin protein family. Mucin family members are glycoproteins that have tandem repeats which are extensively O-glycosylated. The structural features of mucin proteins are responsible for the gel-like properties of mucus. The encoded protein may be involved in disruption of the ocular surface in Sjogren syndrome. [provided by RefSeq, Apr 2014]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (REVEL=0.036).
