- A recurrent c.-14C>T variant has been reported in many patients with type V OI. It introduces an alternative in-frame start codon upstream that is stronger than the reference start codon in transfected HEK cells (PMIDs: 22863190, 22863195). However, the effect of mutant protein (5 amino acids longer) remains unknown but neomorphic mechanism is a widely accepted hypothesis (PMIDs: 25251575, 32383316).

- Missense p.(S40L) variant has a different disease mechanism to that of the recurrent 5'UTR variant: SERPINF1 gene expression and PEDF secretion was increased by the 5'UTR variant but decreased by the p.(S40L) substitution (PMID: 24519609).
