PMID:39963794 reported a kindred with multiple members affected by arrhythmogenic cardiomyopathy (ACM) cosegregating with biallelic TAX1BP3 variants (~28 kb deletion encompassing the entire gene and missense variant p.(Met78Thr)). Three affected siblings from the family had the bialleic variants which were absent in an unaffected sister. Carrier parents were normal.

Experimental work on patient-derived induced pluripotent stem cell cardiac myocytes and a knockout mouse model showed that loss of TAX1BP3 causes calcium dysregulation in cardiomyocytes, which is a known mechanism for arrhythmia.

This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.
