Eleanor Williams commented on gene: SLC52A3: Associated with Brown-Vialetto-Van Laere syndrome 1 #211530 (AR) in OMIM, a form of progressive bulbar palsy with sensorineural deafness. Multiple cases of variants in this gene have been found in patients with Brown-Vialetto-Van Laere syndrome 1: PMID: 20206331 Green et al 2010 - identified homozygous or compound heterozygous variants in C20orf54 (SLC52A3) in individuals with Brown-Vialetto-Van Laere syndrome from 7 families of European, Pakistani and Arabic ancestry. Nonsense and missense variants were found. Used homozgyosity mapping in the first family and then candidate gene analysis. They also report that 58 cases have been documented in the literature, with the age at onset ranged from infancy to early in the third decade, with the majority presenting in the second decade. Hearing loss preceded the onset of neurological signs in most cases. C20ORF54 is thought to play a role in riboflavin transport. PMID: 20920669 Johnson et al 2010 - performed exome sequencing in patients with Brown-Vialetto-van Laere syndrome. In one patient in common with Green et al 2010 they found compound heterozygous variants in C20orf54 (patient 2008-410) rather than the homozygous variant Green et al reported (case 4). The results were confirmed by Sanger sequence and the parents were found to each have 1 heterozygous variant. They also report an additional family (DZ) from Eastern Turkey with a homozygous variant in affected individuals. |

Eleanor Williams gene: SLC52A3 was added gene: SLC52A3 was added to Hearing loss. Sources: Expert list Mode of inheritance for gene: SLC52A3 was set to Unknown Added comment: Gene suggested for panel by Dr Julia Rankin (Royal Devon and Exeter NHS Foundation Trust). Sensorineural deafness is the presenting feature in cases presenting after infancy with other neurology a year or 2 later – treatment with Riboflavin can be effective. Sources: Expert list |
