We report a 37-year-old woman with an out-of-hospital cardiac arrest caused by ventricular fibrillation due to digenic inheritance of long QT syndrome type 2 ( gene) and type 6 ( gene). During hospitalization, prolonged QTc intervals and frequent episodes of ventricular tachyarrhythmias manifested. Genetic testing identified a mutation of the gene and an unclassified variant, most likely pathogenic, of the gene. This digenic inheritance is extremely rare.

Objectives: To report a case of adult-onset non-dystrophic myotonia complicated by recurrent episodes of laryngospasm.
Methods: The patient is a 35-year-old man who was admitted to our hospital for recurrent episodes of apnea requiring endotracheal intubation with mechanical ventilation. He underwent extensive evaluation, including EMG, laryngoscopy, muscle biopsy, and genetic testing, which revealed a diagnosis of non-dystrophic myotonia.
We present a family with two male siblings diagnosed with a newly described digenic myopathy, involving likely pathogenic loss-of-function variants in the SRPK3 and TTN genes: hemizygous p.(Pro68ArgfsTer55) and heterozygous p.(Trp14174Ter), respectively.

Article Synopsis
- *This study focused on the genetic causes of HI in the Malian population through whole exome sequencing, uncovering variants in multiple known HI genes and identifying a novel candidate gene, UBFD1.
- *Results showed that 75% of the examined families had identifiable causes for HI, with many variants being newly identified and a case of digenic inheritance observed.
Article Synopsis
- - The study investigates laterality defects, focusing on the genetic variations linked to congenital heart disease (CHD) by analyzing sequencing data from three cohorts, uncovering a higher occurrence of digenic variants compared to control groups.
- - A digenic model involving 115 known laterality defect genes revealed significant rates of trans-heterozygous digenic variants in affected individuals, particularly in the Baylor, Kids First, and PCGC cohorts (ranging from 2.8% to 13.5%).
- - The results suggest that epistatic interactions between genes play a crucial role in the genetics of laterality defects, with 23% of identified digenic pairs found in structural complexes of motile
