We report on a family with a recessively inherited form of JOAG. The proband has a superior and an inferior never fiber layer thinning in both the eyes and the nasal visual field (VF) defects in the left eye, which are clinical findings consistent with glaucomatous optic neuropathy. Whole exome sequencing revealed two novel compound heterozygous variants [c.2966C&gt;G, p.(Pro989Arg); c.5235T&gt;G, p.(Asn1745Lys)] in latent transforming growth factor-beta-binding protein 2 (LTBP2) segregating with the phenotype. Both these variants are predicted to replace evolutionary conserved amino acids, have a pathogenic effect on the encode protein, and have very low frequencies in the control databases. Mutations in LTBP2 are known to cause the Weill-Marchesani syndrome and a Weill-Marchesani-like syndrome, which include glaucoma in their clinical presentation. However, to our knowledge, this is the first published case of a JOAG subject associated with recessively inherited variants of LTPB2 and, thus, expands the repertoire of the known genetic causes of JOAG and the phenotypic spectrum of LTBP2 alleles.<\/jats:p>","DOI":"10.3390\/genes9110527","type":"journal-article","created":{"date-parts":[[2018,10,31]],"date-time":"2018-10-31T03:50:56Z","timestamp":1540957856000},"page":"527","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Delineation of Novel Compound Heterozygous Variants in LTBP2 Associated with Juvenile Open Angle Glaucoma"],"prefix":"10.3390","volume":"9","author":[{"given":"Osamah","family":"Saeedi","sequence":"first","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sairah","family":"Yousaf","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joby","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathleen","family":"Palmer","sequence":"additional","affiliation":[{"name":"Program of Personalized and Genomic Medicine, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saima","family":"Riazuddin","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2914-4502","authenticated-orcid":false,"given":"Zubair M.","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Maryland School of Medicine, Baltimore, MD 21201, USA"},{"name":"Department of Otorhinolaryngology Head and Neck Surgery, University of Maryland School of Medicine, Baltimore, MD 21201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1016\/S0140-6736(04)16257-0","article-title":"Primary open-angle glaucoma","volume":"363","author":"Weinreb","year":"2004","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"532","DOI":"10.1001\/archopht.122.4.532","article-title":"Prevalence of open-angle glaucoma among adults in the United States","volume":"122","author":"Friedman","year":"2004","journal-title":"Arch.
