Metabolic epilepsy in hyperprolinemia type II due to a novel nonsense ALDH4A1 gene variant

Abstract Hyperprolinemia type II (HPII) is a rare autosomal recessive disorder of proline degradation pathway due to deficiency of delta-1-pyrroline-5-carboxylate dehydrogenase. Pathogenic variants in the ALDH4A1 gene are responsible for this disorder. We here describe an 11-month-old infant with re...

520			\|a Abstract Hyperprolinemia type II (HPII) is a rare autosomal recessive disorder of proline degradation pathway due to deficiency of delta-1-pyrroline-5-carboxylate dehydrogenase. Pathogenic variants in the ALDH4A1 gene are responsible for this disorder. We here describe an 11-month-old infant with recurrent seizures refractory to multiple antiepileptic drugs. She was hospitalized in view of acute-onset encephalopathy, exacerbation of generalized seizures following an upper respiratory infection. Laboratory investigation revealed significantly elevated proline levels in dried blood spots. DNA sample of the child was subjected to a targeted next-generation sequencing gene panel for hyperprolinemias. We detected a novel nonsense homozygous variant in the ALDH4A1 gene in the child and the heterozygous variant of the same in both the parents. Based on the location of the variant i.e. in the last exon, truncated protein is expected to be expressed by skipping nonsense-mediated decay and such point-nonsense variants could be an ideal target for readthrough drugs to correct genetic defects.

Pathogenic variants in the ALDH4A1 gene are responsible for this disorder. We here describe an 11-month-old infant with recurrent seizures refractory to multiple antiepileptic drugs. She was hospitalized in view of acute-onset encephalopathy, exacerbation of generalized seizures following an upper respiratory infection. Laboratory investigation revealed significantly elevated proline levels in dried blood spots. DNA sample of the child was subjected to a targeted next-generation sequencing gene panel for hyperprolinemias. We detected a novel nonsense homozygous variant in the ALDH4A1 gene in the child and the heterozygous variant of the same in both the parents. Based on the location of the variant i.e. in the last exon, truncated protein is expected to be expressed by skipping nonsense-mediated decay and such point-nonsense variants could be an ideal target for readthrough drugs to correct genetic defects.

Pathogenic variants in the ALDH4A1 gene are responsible for this disorder. We here describe an 11-month-old infant with recurrent seizures refractory to multiple antiepileptic drugs. She was hospitalized in view of acute-onset encephalopathy, exacerbation of generalized seizures following an upper respiratory infection. Laboratory investigation revealed significantly elevated proline levels in dried blood spots. DNA sample of the child was subjected to a targeted next-generation sequencing gene panel for hyperprolinemias. We detected a novel nonsense homozygous variant in the ALDH4A1 gene in the child and the heterozygous variant of the same in both the parents. Based on the location of the variant i.e. in the last exon, truncated protein is expected to be expressed by skipping nonsense-mediated decay and such point-nonsense variants could be an ideal target for readthrough drugs to correct genetic defects.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hyperprolinemia</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Refractory seizures</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Proline</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Metabolic epilepsy</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Inborn error of metabolism</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Paria, Pradip</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Saini, Arushi Gahlot</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Suthar, Renu</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bhatia, Vikas</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Attri, Savita Verma</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Metabolic brain disease</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1986</subfield><subfield code="g">36(2021), 6 vom: 26.

abstract	Abstract Hyperprolinemia type II (HPII) is a rare autosomal recessive disorder of proline degradation pathway due to deficiency of delta-1-pyrroline-5-carboxylate dehydrogenase. Pathogenic variants in the ALDH4A1 gene are responsible for this disorder. We here describe an 11-month-old infant with recurrent seizures refractory to multiple antiepileptic drugs. She was hospitalized in view of acute-onset encephalopathy, exacerbation of generalized seizures following an upper respiratory infection. Laboratory investigation revealed significantly elevated proline levels in dried blood spots. DNA sample of the child was subjected to a targeted next-generation sequencing gene panel for hyperprolinemias. We detected a novel nonsense homozygous variant in the ALDH4A1 gene in the child and the heterozygous variant of the same in both the parents. Based on the location of the variant i.e. in the last exon, truncated protein is expected to be expressed by skipping nonsense-mediated decay and such point-nonsense variants could be an ideal target for readthrough drugs to correct genetic defects. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2021
