Description

The IFIH1 c.1641+1G>C variant has been reported in three unrelated individuals that required noninvasive ventilatory support for respiratory syncytial virus bronchiolitis (Asgari S et al., PMID: 28716935). This variant occurs within the canonical splice donor site, which is predicted to cause skipping of the eighth exon, leading to an in-frame transcript. The highest population minor allele frequency in the population database genome aggregation database (v.2.1.1) is 1.07% in the European non-Finnish population. This variant has been reported in the ClinVar database as a germline variant of uncertain significance for Immunodeficiency 95 and benign for Aicardi-Goutieres syndrome 7 and Singleton-Merten syndrome 1. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time.
