Other variants in the same genes have been seen in other studies, such as in Singapore, where Loh et al. described a case report of a patient with a homozygous variant in APOA5 and a heterozygous common variant in GPIHBP1 who presented with subarachnoid hemorrhage with lactescent appearance [38]. This evidence concerns the gene GPIHBP1 and subarachnoid hemorrhage.
