Genes affected

MCOLN3 (HGNC:13358): (mucolipin TRP cation channel 3) This gene encodes one of members of the mucolipin cation channel proteins. Mutation studies of the highly similar protein in mice have shown that the protein is found in cochlea hair cells, and mutant mice show early-onset hearing loss and balance problems. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

MCOLN3 links:

DNAI3 (HGNC:30711): (dynein axonemal intermediate chain 3) Enables Arp2/3 complex binding activity. Involved in negative regulation of Arp2/3 complex-mediated actin nucleation and negative regulation of cell migration. Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.409T>C (p.Y137H) alteration is located in exon 4 (coding exon 3) of the MCOLN3 gene. This alteration results from a T to C substitution at nucleotide position 409, causing the tyrosine (Y) at amino acid position 137 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
