Hereditary ataxia with onset in adulthood v4.15 TDP1 Achchuthan Shanmugasundram Tag Q3_23_promote_green tag was added to gene: TDP1.
Hereditary ataxia with onset in adulthood v4.15 TDP1 Achchuthan Shanmugasundram edited their review of gene: TDP1: Changed rating: GREEN
Hereditary ataxia with onset in adulthood v4.15 TDP1 Achchuthan Shanmugasundram changed review comment from: Comment on list classification: This gene can now be promoted to AMBER as there are three unrelated cases. The "founder-effect" tag has been added as they are all of Middle Eastern descent and harboured the same homozygous variant. However, the additional patient reported by Ian Berry (Leeds Genetics Laboratory) had the same variant in compound heterozygous state with another novel variant. Hence, this gene can be considered for promotion to GREEN rating at the next major review.; to: Comment on list classification: This gene can now be promoted to AMBER as there are three unrelated cases. The "founder-effect" tag has been added as they are all of Middle Eastern descent and harboured the same homozygous variant.

Hereditary ataxia with onset in adulthood v4.6 TDP1 Achchuthan Shanmugasundram changed review comment from: As reviewed by Ian Berry (Leeds Genetics Laboratory), there are now three unrelated families reported in literature with Spinocerebellar ataxia with axonal neuropathy-1 (SCAN1) and identified with homozygous variant in TDP1 gene. However, all three families are of Arab descent (one family from Saudi Arabia and two families from Oman) and they presented with the same homozygous variant (p.His493Arg).

There are a number of functional studies characterising the function of H493R variant in vitro (PMIDs:15920477, 17948061 & 31723605)
