Congenital nystagmus
Gene: ROM1
Variant in this gene are proposed to have a digenic/modifying affect with PRPH2 gene variants for retinal disease.
PMID: 8202715. Digenic retinitis pigmentosa reported in three families with a PRPH2 gene missense p.(Leu185Pro) and one of two different ROM1 gene PTC variants. Carriers of either variant were unaffected. Nystagmus not reported.

PMID: 32716032 - Strayve et al 2020 - created mouse models to look at the effects of eliminating one allele of Rom1 (Rom1+/−) in three different Prph2 models which mimic human disease: C213Y Prph2 (Prph2C/+), K153Del Prph2 (Prph2K/+) and R172W (Prph2R172W).
Reducing Rom1 when there was no Prph2 mutations (Rom1+/−) had no effect on retinal structure or function. But reducing Rom1 in the presence of Prph2 mutations were highly variable ranging from improved rod and cone function to worsened rod and cone function and exacerbated retinal degeneration.Created: 6 Oct 2020, 2:17 p.m. | Last Modified: 6 Oct 2020, 2:17 p.m.
