Case presentation: We present the first Bulgarian genetically confirmed patient with OCRL. The patient had facial dysmorphism, cryptorchidism, congenital cataracts, nystagmus, delayed physical and mental development, and poor nutritional status. He had severe rickets, metabolic acidosis, hypokalaemia, hypophosphataemia, and low IGF-1 levels at the age of three, in addition to his developmental delay. The molecular-genetic analysis reported a pathogenic variant c.1124A&gt;G, p.H375R in the OCRL gene. This variant was inherited from the mother, who was a carrier. Following the diagnosis of OCRL, treatment with potassium citrate, phosphate, and calcitriol was initiated, along with an increase in caloric intake. Following general physical and biochemical improvement, therapy with rhGH started 4 years ago, and current results are presented. Conclusion: The patient with L\u00f6we syndrome who was presented with a 6-year follow-up demonstrates the complexity of rare disease cases and the value of multidisciplinary care together with growth hormone treatment for better results in these patients.<\/jats:p>","DOI":"10.3390\/children10071166","type":"journal-article","created":{"date-parts":[[2023,7,5]],"date-time":"2023-07-05T00:33:42Z","timestamp":1688517222000},"page":"1166","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Initial Effect of Recombinant Human Growth Hormone Treatment in a Patient with L\u00f6we Syndrome"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4160-1200","authenticated-orcid":false,"given":"Violeta","family":"Iotova","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Medical University Varna, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1328-1070","authenticated-orcid":false,"given":"Teodora","family":"Karamfilova","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Medical University Varna, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9358-7263","authenticated-orcid":false,"given":"Mariya","family":"Levkova","sequence":"additional","affiliation":[{"name":"Department of Medical Genetics, Medical University Varna, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariya","family":"Gaydarova","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Nephrology and Dialysis, Medical University Sofia, 1000 Sofia, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3043-6740","authenticated-orcid":false,"given":"Sonya","family":"Galcheva","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Medical University Varna, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitrichka","family":"Bliznakova","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Medical University Varna, 9000 Varna, Bulgaria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,5]]},"reference":[{"key":"ref_1","first-page":"104","article-title":"Ophthalmological finding in a patient with Lowe syndrome","volume":"74","author":"Gerinec","year":"2018","journal-title":"Czech Slovak Ophtalmol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1186\/1750-1172-1-16","article-title":"Lowe syndrome","volume":"1","author":"Loi","year":"2006","journal-title":"Orphanet J.
