MAGEL2MAGE-like protein 2Disease-causing germline mutation(s) (loss of function) inDesconhecido
FUNÇÃO

Probably enhances ubiquitin ligase activity of RING-type zinc finger-containing E3 ubiquitin-protein ligases, possibly through recruitment and/or stabilization of the Ubl-conjugating enzyme (E2) at the E3:substrate complex. Acts as a regulator of retrograde transport via its interaction with VPS35. Recruited to retromer-containing endosomes and promotes the formation of 'Lys-63'-linked polyubiquitin chains at 'Lys-220' of WASHC1 together with TRIM27, leading to promote endosomal F-actin assembly

The Diagnostic and Therapeutic Challenges of Schaaf-Yang Syndrome: A Brazilian Case Report.

Journal of child neurology2026 Mar

Background: Schaaf-Yang syndrome is an ultra-rare neurodevelopmental disorder caused by pathogenic variants in the MAGEL2 gene, also implicated in Prader-Willi syndrome. With less than 1 case per 50 000 people, Schaaf-Yang syndrome remains underreported globally, and no previous cases have been documented in Brazil. Case description: This study presents a 4-year-old Brazilian girl clinically diagnosed with Prader-Willi syndrome, characterized by hypotonia, delayed neuropsychomotor development, and craniofacial dysmorphism. Initial assessments identified growth hormone deficiency and developmental delays, followed by genetic sequencing at 2 years of age, confirming a pathogenic MAGEL2 variant [NM_019066.5:c2821dup: p (Arg941Profs*10)]. The child was also diagnosed with autism spectrum disorder. Multidisciplinary interventions, including medical care, speech therapy, and psychological support, led to remarkable improvements in motor function, language, memory, and learning. Conclusions: This is the first documented Brazilian case of Schaaf-Yang syndrome, emphasizing the critical role of early diagnosis and personalized interventions in reducing the impact of the syndrome.

Identification of a De Novo MAGEL2 Pathogenic Variant in Schaaf-Yang Syndrome and the Importance of Paternal Allele Confirmation.

Journal of clinical laboratory analysis2026 Feb

Schaaf-Yang syndrome (SYS) is a rare genetic disorder caused by pathogenic variants in MAGEL2, a paternally expressed and maternally imprinted gene on 15q11.2. Genetic diagnosis of SYS is challenging due to clinical features that overlap with those of other rare syndromic disorders and limited clinician awareness regarding the diagnosis of imprinting disorders. We present a neonate presenting with respiratory distress and joint contractures, diagnosed with SYS through comprehensive genetic testing. Whole-exome sequencing identified a heterozygous de novo nonsense variant in MAGEL2 c.2092G>T [p.(Gly698Ter)]. To confirm the paternal origin of this variant, methylation-sensitive restriction enzyme digestion followed by long-range PCR, nested PCR, and Sanger sequencing was performed. The MAGEL2 c.2092G>T was absent in both parents, indicating a de novo mutation. Methylation analysis confirmed that the variant resided on the paternal allele, establishing its pathogenicity. A proband diagnostic approach integrating sequence analysis, parental testing, and methylation assays effectively delineates MAGEL2 variants and their inheritance patterns. Our study underscores the importance of combining genomic sequencing with methylation assay to accurately diagnose SYS, especially for de novo variants. The proposed diagnostic workflow facilitates reliable identification of pathogenic MAGEL2 mutations and their parental origin, improving diagnostic precision in clinical settings. Further research is needed to elucidate the molecular mechanisms underlying MAGEL2-related disorders and develop targeted therapies.

MAGEL2 (patho-)physiology and Schaaf-Yang syndrome.

Developmental medicine and child neurology2025 Jan

Schaaf-Yang syndrome (SYS) is a complex neurodevelopmental disorder characterized by autism spectrum disorder, joint contractures, and profound hypothalamic dysfunction. SYS is caused by variants in MAGEL2, a gene within the Prader-Willi syndrome (PWS) locus on chromosome 15. In this review, we consolidate decades of research on MAGEL2 to elucidate its physiological functions. Moreover, we synthesize current knowledge on SYS, suggesting that while MAGEL2 loss-of-function seems to underlie several SYS and PWS phenotypes, additional pathomechanisms probably contribute to the distinct and severe phenotype observed in SYS. In addition, we highlight recent therapeutic advances and identify promising avenues for future investigation.

In-depth behavioral characterization of a rat model of Schaaf-Yang syndrome.

Scientific reports2025 Oct 30

Schaaf-Yang syndrome (SYS, OMIM #615547) is a rare neurodevelopmental disorder caused by truncating variants in the maternally imprinted MAGEL2 gene. It is characterized by intellectual disability, autism spectrum disorder, joint contractures, and feeding difficulties. Although MAGEL2 is deleted in most cases of Prader-Willi syndrome (PWS, OMIM #176270), SYS presents with more severe symptoms, suggesting pathogenic effects of truncated MAGEL2 beyond a mere loss of function. This study expands the behavioral characterization of a novel rat model ("Magel2Pmut rats") which carries a truncating mutation on the paternal allele of Magel2, offering greater construct validity for SYS than previous animal models with Magel2 deletion. While an initial study provided first insights, key domains within the behavioral phenotype of the model remained unexplored. Our comprehensive behavioral analysis, including home-cage monitoring, ultrasonic vocalization analysis, and precise gait assessment, identified several phenotypic alterations potentially relevant to the study of SYS. Magel2Pmut rats exhibited abnormal feeding behavior, changes in early social communication, alterations in gait, aberrant behavior in the elevated plus maze, and delayed decision-making. Additionally, we confirmed that Magel2Pmut rats show phenotypes of abnormal social interaction. These results may reflect core symptoms seen in SYS, underscoring the value of this model for preclinical research on pathophysiology and therapeutics.

Atypical Prader-Willi Syndrome Deletions: Insights Into the Complex Regulation and Phenotypic Variability.

Molecular genetics &amp; genomic medicine2025 Aug

This letter discusses two recent reports of Prader–Willi syndrome (PWS) cases with atypical deletions within the 15q11.2 region. The genetic and clinical complexity highlights the need for caution when interpreting individual cases, supports a symptom‐based management approach, and calls for controlled experimental research to elucidate the regulatory landscape of the PWS locus.
