Towards a suggestive facial dysmorphism in adenylosuccinate lyase deficiency?
Adenylosuccinate lyase deficiency (MIM 103050, ADSL) is a rare autosomal recessive disease causing severe mental retardation and/or autistic features. 2 Seizures are often observed (80%), varying in age of onset (from newborn to late childhood) and nature (tonic-clonic, “suppression burst” pattern, West syndrome, etc), and are very often resistant to all medication. Around 50% of the children s...
متن کاملA mild form of adenylosuccinate lyase deficiency in absence of typical brain MRI features diagnosed by whole exome sequencing
BACKGROUND Adenylosuccinate lyase (ADSL) deficiency is a defect of purine metabolism affecting purinosome assembly and reducing metabolite fluxes through purine de novo synthesis and purine nucleotide recycling pathways. The disorder shows a wide spectrum of symptoms from slowly to rapidly progressing forms. The most severe form is characterized by neonatal encephalopathy, absence of spontaneou...
متن کاملSyndromic Intellectual Disability Caused by a Novel Truncating Variant in AHDC1: A Case Report
Mutations in the AHDC1 gene are associated with the Xia-Gibbs syndrome (XGS), a sporadic genetic disorder characterised by developmental delay, intellectual disability, hypotonia, obstructive sleep apnoea, dysmorphic facial features, and cerebral malformations with plagiocephaly. Here we report the case of a 13-year-old Colombian female patient with a history of developmental delay, speech dela...
متن کاملPrevalence of adenylosuccinate lyase deficiency based on aggregated exome data
We readwith great interest the recent paper byDonti et al. [1] on the diagnosis of adenylosuccinate lyase deficiency via plasma metabolomics. In their Supplementary Table S3, the authors provide the allele frequency for previously reported ADSLmutations. Based on this data, and adding the allele frequency of other pathogenic variants, one can estimate the minimal prevalence of the disease. The ...
متن کاملClinical, biochemical and molecular genetic correlations in adenylosuccinate lyase deficiency.
Adenylosuccinate lyase (ADSL) deficiency (MIM 103050) is an autosomal recessive inborn error of purine synthesis characterized by the accumulation in body fluids of succinylaminoimidazolecarboxamide (SAICA) riboside and succinyladenosine (S-Ado), the dephosphorylated derivatives of the two substrates of the enzyme. Because ADSL-deficient patients display widely variable degrees of psychomotor r...
