A Novel Phenotypic Presentation of Absence Seizures in a 15-Month-Old with PIGK-Related GPI Biosynthesis Disorder: A Case Report.

Case reports in neurology2026

PIGK-related glycosylphosphatidylinositol (GPI) biosynthesis disorder is an extremely rare neurodevelopmental condition, with only 12 cases described to date. It is caused by biallelic mutations in the PIGK gene, which encodes a catalytic subunit of the GPI transamidase complex. This enzyme facilitates the attachment of GPI anchors to proteins crucial for cellular signaling and development. Eight of the 12 described cases were reported to have seizures, but the electroclinical characteristics are not well defined. We report a 15-month-old female who presented with global developmental delay, hypotonia, oral dysphagia, nystagmus, and cerebellar atrophy on MRI. Abnormal movements occurred at 10 months of age with intermittent, brief right arm tremors initially presumed to be benign myoclonus of infancy. However, subsequent 24-h video EEG revealed classic 3-Hz generalized spike-and-wave discharges with clinical correlates of behavioral arrest previously unrecognized, confirming a diagnosis of absence seizures - a feature not previously reported in the literature for PIGK-related disorders. Whole exome sequencing confirmed biallelic PIGK pathogenic variants. To our knowledge, this is the first reported case of typical absence seizures with 3-Hz generalized spike-and-wave discharges in a very young patient with confirmed PIGK mutation. Our report expands the known electroclinical phenotype of GPI-anchor deficiencies, suggesting the need to screen for subtle generalized epilepsy syndromes like absence, among affected infants. This case highlights a novel EEG phenotype in PIGK-related GPI biosynthesis disorder underscoring the relevance of early EEG evaluation in infants with this extremely uncommon neurogenetic disorder.

Generation of BBSOAS patient-specific induced pluripotent stem cell lines harboring six NR2F1 pathogenic variants.

Stem cell research2026 Mar 10

Bosch-Boonstra-Schaaf Optic Atrophy Syndrome (BBSOAS) is a rare autosomal dominant neurodevelopmental disorder caused by mutations or deletions in NR2F1, leading to intellectual disability, developmental delay, visual impairments, epilepsy, hypotonia, and autistic traits. We generated six novel human induced pluripotent stem cell (hiPSC) lines from BBSOAS patients with variable clinical phenotypes. These lines provide a versatile and renewable resource by serving as a unique platform to model NR2F1-related developmental defects in vitro and elucidate the molecular and cellular mechanisms underlying BBSOAS. Their availability will facilitate mechanistic, comparative, and therapeutic studies, advancing our understanding of NR2F1 function in human neural development.

Systematic analysis of homozygous autosomal copy number losses in exomes improves diagnostic yield and uncovers ultra-rare recessive disorders.

medRxiv : the preprint server for health sciences2026 Jan 27

Systematic analysis of copy number variants (CNVs) in large datasets is challenging and there are limited studies of homozygous copy number losses in rare disease exome datasets. Here we leveraged the genomic uniqueness and relative under-representation of the Indian population in the current public genomic databases and identified 42,386 possible homozygous losses (median count 20 per individual, range 0 - 55; median size 2.95 kb, range 99 bp - 4.76 Mb) in a heterogeneous cohort of 2,021 individuals with suspected Mendelian disorders, who had undergone exome sequencing using 12 different capture kits in a resource-limited setting. Employing a genomic position loss-count based approach, we filtered 1,224 rare homozygous loss calls in 718 individuals (median count 1 per individual, range 0 - 22; median size 3.49 kb, range 121 bp - 4.76 Mb) for further analysis, thus significantly reducing the analysis burden. Clinical correlation and validation of these rare calls enabled 10 new diagnoses in 240 unsolved individuals with at least one filtered rare homozygous loss call. This, led to nearly two-fold increase in diagnosis owing to homozygous deletions in our cohort. Further analysis of the data and identification of additional affected individuals through collaboration led to identification of biallelic FILIP1 and FAM177A1 variants as causes of a syndromic arthrogryposis and a neuromuscular disorder respectively. Both these conditions have been recently proven as ultra-rare recessive disorders, thus validating our approach. We also show that biallelic loss-of-function TFCP2L1 variants cause chronic kidney disease and VPS36 variants cause a severe recessive neurodevelopmental disorder characterised by microcephaly, motor delay, agenesis of the corpus callosum, cerebellar atrophy, seizures, hypotonia, spasticity and early death. Overall, these results demonstrate a scalable approach to screen homozygous losses for improving diagnostic yield and discovering disease-genes in large exome cohorts.

Neuroimaging of tic disorders.

Handbook of clinical neurology2026

Gilles de la Tourette syndrome (GTS) is increasingly conceptualized as a neurodevelopmental network disorder. In this chapter, we have synthesized two decades of neuroimaging findings spanning gray- and white-matter morphology, structural connectivity, and functional network dynamics in GTS across childhood and adulthood. Structural MRI studies using voxel-based morphometry (VBM) have reported heterogeneous volume differences-both decreases and increases-across cortico-striatal-thalamo-cortical regions, motivating the use of meta-analytic approaches to identify more consistent loci, including cingulate, sensorimotor, thalamic, striatal, and insular regions. In contrast, cortical thickness studies more consistently indicate cortical thinning in motor/premotor and prefrontal areas, with links to tic phenomenology and premonitory urges. Diffusion and volumetric white-matter measures further implicate interhemispheric pathways and fronto-striatal projections, with some indices relating to tic severity. At the circuit level, tractography and structural covariance studies support altered connectivity within the cortico-striato-pallido-thalamo-cortical loop and highlight a complementary contribution of cerebello-cortical pathways. Functional MRI studies converge on temporally structured node engagement during tic generation-preceding activity in supplementary motor, cingulate, insular, and opercular regions, followed by sensorimotor, thalamic, and cerebellar involvement-and reveal large-scale reconfiguration of cortico-basal ganglia networks associated with tic severity and comorbid symptoms. Finally, lesion-network mapping and coordinate-based network mapping studies in secondary tics and GTS-related atrophy converge on a common tic-associated network, providing a translational framework to guide neuromodulation and to derive clinically meaningful network biomarkers for treatment targeting.

The Phenotypic Spectrum of Miller Syndrome: Insight From a French Cohort.

Clinical genetics2026 Jan

Miller syndrome (MIM#263750) is a rare autosomal recessive acrofacial dysostosis associated with biallelic DHODH variants. Since the identification of the gene in 2010, five case reports have described a variable phenotype in only nine individuals from eight families. We present a cohort of 10 individuals from seven families affected by Miller syndrome, spanning the prenatal stage to 46 years of age. We report on the largest cohort of Miller syndrome to date, which highlights novel findings, including optic atrophy in multiple members of one consanguineous family. The typical postaxial limb defects, including the absence of the 5th digit, were consistent with prior descriptions, but we highlighted the frequent involvement of preaxial structures (thumb and tibial hypoplasia). A higher incidence of camptodactyly and the presence of facial nevus in two patients were notable findings. Congenital heart defects, primarily atrial septal defects, were common, and all living individuals had normal neurodevelopment. This cohort expands the phenotypic spectrum of Miller syndrome associated with variation in DHODH, presenting new findings such as preaxial involvement and facial nevus simplex. Optic atrophy in one family could prompt screening of other cases. Early prenatal diagnosis, particularly in the presence of cardinal limb and cardiac malformations, is crucial for management and genetic counseling.
