Genes affected
TOMT (HGNC:55527): (transmembrane O-methyltransferase) This gene encodes a catechol-O-methyltransferase that catalyzes the transfer of a methyl group from S-adenosyl-L-methionine to a hydroxyl group of catechols and is essential for auditory and vestibular function. Mutations in this gene have been associated with nonsyndromic deafness. Readthrough transcription is observed across this gene and the adjacent leucine-rich repeat containing 51 gene. A third locus (GeneID:220074) is defined to represent the readthrough transcripts. [provided by RefSeq, Feb 2021]
LRTOMT (HGNC:25033): (leucine rich transmembrane and O-methyltransferase domain containing) This locus represents naturally occurring readthrough transcription between the neighboring LRRC51 (leucine-rich repeat containing 51) and TOMT (transmembrane O-methyltransferase) genes on chromosome 11. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. Multiple reports implicate mutations in this gene in nonsyndromic deafness.[provided by RefSeq, Feb 2021]
ANAPC15 (HGNC:24531): (anaphase promoting complex subunit 15) Involved in regulation of mitotic cell cycle spindle assembly checkpoint. Part of anaphase-promoting complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.003430903).
BP6
Variant 11-72108672-G-A is Benign according to our data. Variant chr11-72108672-G-A is described in ClinVar as Benign. ClinVar VariationId is 44040.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0084 (1279/152278) while in subpopulation NFE AF = 0.0129 (877/68012). AF 95% confidence interval is 0.0122. There are 6 homozygotes in GnomAd4. There are 596 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 6 gene
