Genes affected

MUC15 (HGNC:14956): (mucin 15, cell surface associated) Predicted to be located in Golgi lumen and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

MUC15 links:

ANO3 (HGNC:14004): (anoctamin 3) The protein encoded by this gene belongs to the TMEM16 family of predicted membrane proteins, that are also known as anoctamins. While little is known about the function of this gene, mutations in this gene have been associated with some cases of autosomal dominant craniocervical dystonia. Cells from individuals with a mutation in this gene exhibited abnormalities in endoplasmic reticulum-dependent calcium signaling. Studies in rat show that the rat ortholog of this protein interacts with, and modulates the activity of a sodium-activated potassium channel. Deletion of this gene caused increased pain sensitivity in the rat model system. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.899G>A (p.R300Q) alteration is located in exon 4 (coding exon 3) of the MUC15 gene. This alteration results from a G to A substitution at nucleotide position 899, causing the arginine (R) at amino acid position 300 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
