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]

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.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0045607984).
• BP6: Variant 11-26565803-G-C is Benign according to our data. Variant chr11-26565803-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 235242.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00941 (1415/150294) while in subpopulation AFR AF= 0.032 (1324/41326). AF 95% confidence interval is 0.0306. There are 26 homozygotes in gnomad4. There are 681 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 26 AR gene
