Childhood onset dystonia, chorea or related movement disorder v1.212 IMPDH2 Sarah Leigh Tag Q3_21_rating was removed from gene: IMPDH2.
Childhood onset dystonia, chorea or related movement disorder v1.212 IMPDH2 Sarah Leigh commented on gene: IMPDH2
Childhood onset dystonia, chorea or related movement disorder v1.211 IMPDH2 Sarah Leigh Source Expert Review Green was added to IMPDH2.

Childhood onset dystonia, chorea or related movement disorder v1.156 IMPDH2 Arina Puzriakova Publications for gene: IMPDH2 were set to 33098801
Childhood onset dystonia, chorea or related movement disorder v1.155 IMPDH2 Arina Puzriakova Classified gene: IMPDH2 as Amber List (moderate evidence)
Childhood onset dystonia, chorea or related movement disorder v1.155 IMPDH2 Arina Puzriakova Added comment: Comment on list classification: This gene is not yet associated with a relevant phenotype in OMIM or G2P, but there are sufficient unrelated cases (3) presenting with signs of dystonia to rate as Green at the next GMS review. Other cases reported with motor dysfunction, and it is plausible that this may develop into dystonia later in life.
Childhood onset dystonia, chorea or related movement disorder v1.155 IMPDH2 Arina Puzriakova Gene: impdh2 has been classified as Amber List (Moderate Evidence).
Childhood onset dystonia, chorea or related movement disorder v1.154 IMPDH2 Arina Puzriakova Deleted their comment
Childhood onset dystonia, chorea or related movement disorder v1.154 IMPDH2 Arina Puzriakova edited their review of gene: IMPDH2: Added comment: Kuukasjärvi et al., 2021 (PMID: 34305140) report on an additional large Finnish family (6 affected members) with a heterozygous truncating variant co-segregating with a dominantly inherited dystonia-tremor phenotype. Patient fibroblasts showed reduced IMPDH2 expression. IMPDH2 is the rate-limiting enzyme in the biosynthesis of guanine nucleotides, a dopamine synthetic pathway previously linked to childhood or adolescence-onset dystonia disorders.; Changed publications to: 33098801, 34305140
