Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_033049.4(MUC13):c.299T>C(p.Ile100Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.427 in 1,612,616 control chromosomes in the GnomAD database, including 148,363 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/16 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

Genes affected

MUC13 (HGNC:7511): (mucin 13, cell surface associated) Epithelial mucins, such as MUC13, are a family of secreted and cell surface glycoproteins expressed by ductal and glandular epithelial tissues (Williams et al., 2001 [PubMed 11278439]).[supplied by OMIM, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.2903085E-4).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.456 is higher than 0.05.
