Genes affected

MUC7 (HGNC:7518): (mucin 7, secreted) This gene encodes a small salivary mucin, which is thought to play a role in facilitating the clearance of bacteria in the oral cavity and to aid in mastication, speech, and swallowing. The central domain of this glycoprotein contains tandem repeats, each composed of 23 amino acids. This antimicrobial protein has antibacterial and antifungal activity. The most common allele contains 6 repeats, and some alleles may be associated with susceptibility to asthma. Alternatively spliced transcript variants with different 5' UTR, but encoding the same protein, have been found for this gene. [provided by RefSeq, Oct 2014]

The c.893C>T (p.P298L) alteration is located in exon 4 (coding exon 2) of the MUC7 gene. This alteration results from a C to T substitution at nucleotide position 893, causing the proline (P) at amino acid position 298 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
