HsaEX0058019 and HsaEX0058023 are often included together. This splice isoform is associated with increased neuronal viability and mitochondrial elongation. The mitochondrial effect is associated with mitochondrial maintenance and function. Loss of this isoform is suggested to render neurons more susceptible to apoptotic stress.

Isoforms 1b + 1c (represented by joint inclusion of this event and HsaEX0058019), show an antiapoptotic effect in human androgen-sensitive prostate cancer cell lines, while isoform 1a (corresponding to skipping of both exons) shows a pro-apoptotic effect. Isoforms 1b and 1c are up-regulated in patient-derived samples of treatment-induced neuroendocrine prostate cancer, which is a very aggressive and metastatic form of prostate cancer characterised by increased expression of SRRM4 (ENSG00000139767), a known master regulator of microexon inclusion in neuronal-related cell types. In contrast, prostate adenocarcinoma samples predominantly express isoform 1a.
