Arina Puzriakova changed review comment from: Comment on list classification: Early developmental delay, which preceded other progressive neurological concerns, was reported in the three unrelated cases from PMID:30970188. Following discussion with Helen Brittain (Genomics England Clinical Team) it was agreed that this is sufficient for inclusion on this panel. However, detection of this 5' UTR triplet expansion must first be internally validated for the interpretation pipeline. In the meantime, rating Red but will raise the STR for validation with the Rare Disease team.; to: Comment on list classification: Early developmental delay, which preceded other progressive neurological concerns, was reported in the three unrelated cases from PMID:30970188.

Arina Puzriakova STR: GLS_GCA was added STR: GLS_GCA was added to Intellectual disability. Sources: Literature Mode of inheritance for STR: GLS_GCA was set to BIALLELIC, autosomal or pseudoautosomal Publications for STR: GLS_GCA were set to 30970188 Phenotypes for STR: GLS_GCA were set to Global developmental delay, progressive ataxia, and elevated glutamine, OMIM:618412; Global developmental delay, progressive ataxia, and elevated glutamine, MONDO:0032733 Review for STR: GLS_GCA was set to GREEN Added comment: - PMID: 30970188 (2019) - Three unrelated cases who presented with an early-onset global developmental delay, progressive ataxia, and elevated levels of glutamine. One patient also showed cerebellar atrophy. All 3 individuals harboured a large trinucleotide (GCA) repeat expansion in the 5' UTR (length: 680-1,500-copy repeats). The repeat expansion was found in homozygosity in 1 case, and occurred in compound heterozygosity with an SNV in the other two cases (missense and frameshift variant, respectively). Functional analysis showed the repeat expansion results in reduced expression and glutaminase deficiency. Sources: Literature |
