Variant 1-85029150-T-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_018298.11(MCOLN3):c.788A>T(p.Asp263Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000412 in 1,454,950 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D263G) has been classified as Uncertain significance.

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.788A>T (p.D263V) alteration is located in exon 7 (coding exon 6) of the MCOLN3 gene. This alteration results from a A to T substitution at nucleotide position 788, causing the aspartic acid (D) at amino acid position 263 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
