In this study, two SLC52A3 variants (NM_033409.4: c.62A\u2009&amp;gt;\u2009G [p.Asn21Ser] and c.161G\u2009&amp;gt;\u2009A [p.Gly54Glu]) were identified in a family with hereditary hearing loss through whole-exome sequencing. The compound heterozygous proband exhibited only late-onset, progressive, and symmetric sensorineural hearing loss over 23\u00a0yr, along with unilateral facial muscle spasm. A heterozygous carrier of the c.62A\u2009&amp;gt;\u2009G variant also exhibited optic nerve dysfunction, while no other neurological abnormalities were observed in the family. Although the proband\u2019s decreased serum riboflavin level has been improved through supplementation, no significant clinical improvement was observed. These findings further support the phenotypic variability, incomplete penetrance, and a potential autosomal dominant inheritance pattern of RTD3. We also underscore the importance of early genetic testing, timely and sustained riboflavin supplementation, and long-term follow-up in affected individuals.<\/jats:p>","DOI":"10.1093\/hmg\/ddaf155","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T12:04:44Z","timestamp":1759406684000},"page":"1927-1933","source":"Crossref","is-referenced-by-count":2,"title":["Atypical phenotypic characteristics, mutation analysis and treatment in a family of riboflavin transporter deficiency caused by\n                    <i>SLC52A3<\/i>\n                    variants"],"prefix":"10.1093","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6665-7526","authenticated-orcid":false,"given":"Peipei","family":"Li","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2277-1701","authenticated-orcid":false,"given":"Ting","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7895-0899","authenticated-orcid":false,"given":"Hongen","family":"Xu","sequence":"additional","affiliation":[{"name":"Tianjian Laboratory of Advanced Biomedical Sciences, Academy of Medical Sciences, Zhengzhou University , Daxuebei Road No. 40, Erqi Disreict, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengwei","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingying","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziwen","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengli","family":"Zhang","sequence":"additional","affiliation":[{"name":"Tianjian Laboratory of Advanced Biomedical Sciences, Academy of Medical Sciences, Zhengzhou University , Daxuebei Road No. 40, Erqi Disreict, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3992-2139","authenticated-orcid":false,"given":"Xingle","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9087-012X","authenticated-orcid":false,"given":"Bei","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, The First Affiliated Hospital of Zhengzhou University , Jianshe East Road No. 1, Erqi District, Zhengzhou 450052 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,10,8]]},"reference":[{"key":"2025111904120219200_ref1","doi-asserted-by":"publisher","first-page":"1889","DOI":"10.1093\/brain\/115.6.1889","article-title":"Progressive bulbar paralysis of childhood.
