Ophthalmologic findings that may affect any ocular segment including characteristic, small, atonic pupils. WARBM is known to be caused by biallelic, pathogenic variants in at least five genes although additional genetic loci may exist. The RAB3GAP1 c.748 + 1G>A, p.Asp250CysfsTer24 founder variant has been described in families of Turkish ancestry. We report the clinical and molecular findings in three, unrelated, Turkish families with WARBM. A novel c.974-2A>G variant causing WARBM in three siblings of Turkish descent was found. Functional studies of the novel, c.2606 + 1G>A variant in patients\" mRNA revealed skipping of exon 22 which results in a premature stop codon in exon 23. However, the clinical consequences of this variant are blended given that the individual also had a maternally inherited chromosome 3q29 microduplication.enginfo:eu-repo/semantics/openAccessTıpDahili Tıp BilimleriÇocuk Sağlığı ve HastalıklarıTıbbi GenetikCerrahi Tıp BilimleriPatolojiYaşam BilimleriMoleküler Biyoloji ve GenetikSağlık BilimleriTemel Tıp BilimleriAnatomiBiyokimyaTemel BilimlerMedicineInternal Medicine SciencesChild Health and DiseasesMedical GeneticsSurgery Medicine SciencesPathologyLife SciencesMolecular Biology and GeneticsHealth SciencesFundamental Medical SciencesHuman AnatomyBiochemistryNatural SciencesKlinik Tıp (MED)Yaşam Bilimleri (LIFE)Klinik TıpBiyoloji ve BiyokimyaPEDİATRİPATOLOJİANATOMİ VE MORFOLOJİGENETİK VE KALITIMClinical Medicine (MED)Life Sciences (LIFE)CLINICAL MEDICINEBIOLOGY & BIOCHEMISTRYMOLECULAR BIOLOGY & GENETICSPEDIATRICSPATHOLOGYANATOMY & MORPHOLOGYGENETICS & HEREDITYPediatri, Perinatoloji ve Çocuk SağlığıPatoloji ve Adli TıpGenetik (klinik)Pediatrics, Perinatology and Child HealthAnatomyPathology and Forensic MedicineGenetics (clinical)article322556110.1097/mcd.0000000000000454
