Genes affected
MUC21 (HGNC:21661): (mucin 21, cell surface associated) This gene encodes a large membrane-bound glycoprotein which is a member of the mucin family. Mucins are O-glycosylated proteins that play an essential role in forming protective mucous barriers on epithelial surfaces. These proteins also play a role in intracellular signaling. The encoded protein contains an N-terminal signal sequence, an extracellular mucin domain, a stem domain, a transmembrane domain, and a C-terminal cytoplasmic tail domain. The mucin domain contains O-glycosylation sites and is polymorphic with isoforms containing a variable number of nonidentical proline-, threonine-, and serine-rich tandem repeats of 15 amino acids each. The aberrent expression of this gene is associated with lung adenocarcinoma. [provided by RefSeq, May 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.372G>C (p.E124D) alteration is located in exon 2 (coding exon 2) of the MUC21 gene. This alteration results from a G to C substitution at nucleotide position 372, causing the glutamic acid (E) at amino acid position 124 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
