The variant was absent in 251156 control chromosomes in GnomAD. c.15_19delinsATCTT has been reported in the literature in an individual affected with features of Hemoglobinopathy and was in trans along with another pathogenic variant c.92+5G>C in HBB (example: Agarwal_1997). The carrier mother was also reported to have classical beta-thalassemia trait. These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 9371533). No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014.
