Repeat Disorders v0.157 OPDM1 Bryony Thompson Phenotypes for STR: OPDM1 were changed from Oculopharyngodistal myopathy 1 MIM#164310 to Oculopharyngodistal myopathy 1 MIM#164310; Amyotrophic lateral sclerosis MONDO:0004976
Repeat Disorders v0.156 OPDM1 Bryony Thompson Publications for STR: OPDM1 were set to 31332380; 34047774
Repeat Disorders v0.155 OPDM1 Bryony Thompson edited their review of STR: OPDM1: Changed publications: 31332380, 34047774, 37339631
Repeat Disorders v0.155 OPDM1 Bryony Thompson edited their review of STR: OPDM1: Added comment: The CGG repeat expansion in the 5’UTR of LRP12 was identified in 5 ALS families and 2 simplex cases. 61-100 repeats associated with ALS, whereas >100 repeats causes OPDM. Toxic gain-of-function is the mechanism of disease. Authors’ suggest the differences in the levels of toxic RNA and MBNL1 dysfunction, in turn dependent on repeat length, may determine whether the affected individual develops ALS or OPDM; Changed phenotypes: Oculopharyngodistal myopathy 1 MIM#164310, Amyotrophic lateral sclerosis MONDO:0004976

Added comment: NM_013437.5:c.-102CGG[X]
RNA-mediated toxicity is thought to be the mechanism of disease. Sixty-five Japanese patients with oculopharyngodistal myopathy (OPDM) from 59 families with CGG repeat expansions in LRP12. This represents the most common OPDM subtype among all patients in Japan with genetically diagnosed OPDM.
Normal: 13 to 45 repeats.
Pathogenic: 85 to 289 repeats.
