Current testing strategies often fail to provide a comprehensive diagnosis and typically require the use of multiple testing methodologies.

Subjects with no definitive diagnosis from ES subsequently underwent GS. Variants were interpreted using hearing loss\u2013specific ACMG guidelines and published literature.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Three individuals were diagnosed with biallelic pathogenic variants upon\n                      <jats:italic>GJB2<\/jats:italic>\n                      single gene reanalysis. ES identified a definitive or likely diagnosis in five different hearing loss\u2013related genes in 5\/20 (25%) individuals, while two additional cases remained inconclusive due to novel or ambiguous variants in two other hearing loss\u2013associated genes. GS of the remaining 15 cases yielded diagnoses in three individuals, including the identification of deletions in\n                      <jats:italic>LOXHD1<\/jats:italic>\n                      and\n                      <jats:italic>STRC<\/jats:italic>\n                      , and a recently characterized 125\u2009kb deletion overlapping\n                      <jats:italic>CRYL1<\/jats:italic>\n                      , which refines a critical upstream regulatory region associated with\n                      <jats:italic>GJB2<\/jats:italic>\n                      \u2010related hearing loss.
