Infantile‐Onset Ascending Hereditary Spastic Paraplegia due to a Homozygous ALS2 Exons 24–25 Deletion: Expanding the Genotypic Spectrum

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a novel homozygous intragenic deletion in the ALS2 gene in an 8‐year‐old boy with Infantile‐onset Ascending Hereditary Spastic Paraplegia (IAHSP) and oculomotor apraxia, thereby contributing to the expanding genetic landscape of ALS2‐related disorders.

Long‐Read Genome Sequencing Establishes Biallelic Pathogenic Variants in DNM1 With Distinct Functional Effects as the Cause of Early Infantile Developmental and Epileptic Encephalopathy

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous de novo and inherited biallelic pathogenic variants in DNM1 have been reported in association with autosomal dominant (AD) and autosomal recessive (AR) developmental and epileptic encephalopathy, respectively, due to aberrant dynamin function or expression, with each inheritance pattern associated with a different mechanism of ...

Expanding the Genotype–Phenotype Correlation of Marden–Walker Syndrome due to PIEZO2 Gene Variants: A Case Report From Brazil

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marden–Walker syndrome (MWS; OMIM 248700) is an extremely rare congenital disorder characterized by multiple joint contractures, craniofacial dysmorphism, neurological abnormalities, and multisystem involvement. Although historically diagnosed on clinical grounds, only a few cases have been molecularly confirmed.

Effects of sex chromosome dosage on corpus callosum morphology in supernumerary sex chromosome aneuploidies. [PDF]

open access: yes, 2014
BackgroundSupernumerary sex chromosome aneuploidies (sSCA) are characterized by the presence of one or more additional sex chromosomes in an individual's karyotype; they affect around 1 in 400 individuals.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

KARYOTYPE STUDY IN THE SURF CLAM MESODESMA DONACIUM LAMARCK, 1818 (BIVALVIA: VENEROIDA: MESODESMATIDAE) ESTUDIO CARIOTIPICO EN LA MACHA MESODESMA DONACIUM LAMARCK, 1818 (BIVALVIA: VENEROIDA: MESODESMATIDAE)

open access: yesGayana, 2008
Mesodesma donacium is a marine clam distributed from Sechura Bay (5°S) in northern Perú to Chiloé Island (43ºS) in southern Chile. Due to the commercial importance of this species, their populations have been reduced in the later years.
