Case Report: Expanded delineation of phenotype of TRPM3-related neurodevelopmental disorders.

The TRPM3 gene, part of the transient receptor potential (TRP) cation channel family, plays crucial roles in sensory perception and ion transport. Mutations in TRPM3 are linked to a range of neurological and developmental disorders. The c.

A novel non-recurrent CNV deletion involving TBX4 and leaving TBX2 intact causes congenital alveolar dysplasia.

Congenital alveolar dysplasia (CAD) belongs to rare lethal lung developmental disorders (LLDDs) in neonates, manifesting with acute respiratory failure and pulmonary arterial hypertension refractory to treatment. The majority of CAD cases have been associated with copy-number variant (CNV) deletions at 17q23.1q23.

COVID-19 mRNA BNT162b2 vaccine immunogenicity among children with a history of paediatric multisystem inflammatory syndrome temporally associated with COVID-19 (PIMS-TS).

We conducted a prospective cohort study of 20 patients with a history of paediatric multisystem inflammatory syndrome temporally associated with COVID-19 (PIMS group, median age seven years, 70% male) and 34 healthy controls without such a history (CONTROL group, median age eight years, 38% male) aged 5-12 years, to assess the immunogenicity of Pfizer-BioNTech COVID-19 mRNA BNT162b2 vaccine (Comirnaty®). Patients received two doses of COVID-19 mRNA BNT162b2 vaccine (10 ug/dose) 21 days apart. Pre-vaccine anti-S SARS-CoV-2 IgG antibodies were measured on the day of the first dose and at the median of 23 days after the second dose.

COVID-19 mRNA BNT162b2 vaccine safety and B-cell and T-cell reactogenicity among children with a history of paediatric multisystem inflammatory syndrome temporally associated with COVID-19 (PIMS-TS) - preliminary study.

To assess the safety of Pfizer-BioNTech COVID-19 mRNA BNT162b2 vaccine (Comirnaty®) among patients with the anamnesis of paediatric inflammatory syndrome temporally associated with COVID-19 (PIMS-TS), we conducted a prospective cohort study of 21 patients with history of PIMS (PIMS group, median age 7.4 years, 71% male) and 71 healthy controls without such an anamnesis (CONTROL group, median age 9.0 years, 39% male) aged 5-18 years.

Destabilization of mutated human PUS3 protein causes intellectual disability.

Pseudouridine (Ψ) is an RNA base modification ubiquitously found in many types of RNAs. In humans, the isomerization of uridine is catalyzed by different stand-alone pseudouridine synthases (PUS). Genomic mutations in the human pseudouridine synthase 3 gene (PUS3) have been identified in patients with neurodevelopmental disorders.

Severe Infantile Axonal Neuropathy with Respiratory Failure Caused by Novel Mutation in X-Linked Gene.

LAS1L encodes a nucleolar ribosomal biogenesis protein and is also a component of the Five Friends of Methylated CHTOP (5FMC) complex. Mutations in the LAS1L gene can be associated with Wilson−Turner syndrome (WTS) and, much more rarely, severe infantile hypotonia with respiratory failure. Here, we present an eighteen-month old boy with a phenotype of spinal muscular atrophy with respiratory distress (SMARD).

Further Delineation of Developmental Delay with Gastrointestinal, Cardiovascular, Genitourinary, and Skeletal Abnormalities Caused by Gene Mutation.

Until 2021, the gene was not associated with any human genetic disease. There were only two studies exploring the associations between variants in and alcohol dependence. In 2021 Bertoli-Avella et al.

Distinct characteristics of multisystem inflammatory syndrome in children in Poland.

During the winter months of 2020/2021 a wave of multisystem inflammatory syndrome in children (MIS-C) emerged in Poland. We present the results of a nationwide register aiming to capture and characterise MIS-C with a focus on severity determinants. The first MIS-C wave in Poland was notably high, hence our analysis involved 274 children.

Prenatal Versus Postnatal Diagnosis of Meckel-Gruber and Joubert Syndrome in Patients with Mutations.

Renal cystic diseases are characterized by genetic and phenotypic heterogeneity. Congenital renal cysts can be classified as developmental disorders and are commonly diagnosed prenatally using ultrasonography and magnetic resonance imaging. Progress in molecular diagnostics and availability of exome sequencing procedures allows diagnosis of single-gene disorders in the prenatal period.

Variants of ATP1A3 in residue 756 cause a separate phenotype of relapsing encephalopathy with cerebellar ataxia (RECA)-Report of two cases and literature review.

Background: Variants in ATP1A3 cause well-known phenotypes-alternating hemiplegia of childhood (AHC), rapid-onset dystonia-parkinsonism (RDP), cerebellar ataxia, areflexia, pes cavus, optic atrophy, sensorineural hearing loss (CAPOS), and severe early infantile epileptic encephalopathy. Recently, there has been growing evidence for genotype-phenotype correlations in the ATP1A3 variants, and a separate phenotype associated with variants in residue 756-two acronyms are proposed for the moment-FIPWE (fever-induced paroxysmal weakness and encephalopathy) and RECA (relapsing encephalopathy with cerebellar ataxia).

Materials And Methods: Herein, we are describing two new pediatric cases with a p.

Case Report: Further Delineation of Neurological Symptoms in Young Children Caused by Compound Heterozygous Mutation in the Gene.

protein is a unique ion channel that converts mechanical impulses into cellular signals in somatosensory neurons and is involved in various mechanotransduction pathways. The recessive loss-of-function pathogenic variants are associated with distal arthrogryposis with impaired proprioception and touch (DAIPT). Here we present three new DAIPT patients.

Single median maxillary central incisor syndrome and variant in SMO gene associated with SHH pathway.

Solitary median maxillary central incisor syndrome (SMMCI) is a rare congenital oronasal-dental midline anomaly. The aim of this paper is a presentation of a patient with SMMCI without other visible dentofacial anomalies, with a potentially new molecular etiology consisting of a gene-gene reaction and conservative therapeutic approach to nasal obstruction. Potentially pathogenic variants in the SMO gene (p.

HPV vaccine acceptance and hesitancy - lessons learned during 8 years of regional HPV prophylaxis program in Wroclaw, Poland.

In 2019, the WHO has announced that it will intensify efforts to eliminate cervical cancer worldwide by increasing coverage of the HPV (Human Papillomavirus) vaccine. Finding reasons for low HPV vaccine coverage and looking for solutions to address the problem should be the priorities for public health. The municipality of Wroclaw (Poland) attempted to meet the challenge earlier by introducing a Prophylaxis Program against HPV in 2010.

Novel de novo mutation affecting two adjacent aminoacids in the EED gene in a patient with Weaver syndrome.

Overgrowth, macrocephaly, accelerated osseous maturation, variable intellectual disability, and characteristic facial features are the main symptoms of Weaver syndrome, a rare condition caused by mutations in EZH2 gene. Recently, in four patients with Weaver-like symptoms without mutations in EZH2 gene, pathogenic variants in EED were described. We present another patient clinically diagnosed with Weaver syndrome in whom WES revealed an EED de novo mutation affecting two neighboring aminoacids, NM_003797.
