Split hand/split foot malformation (SHFM) or ectrodactyly is characterized by a deep median cleft of the hand or foot, hypoplasia or aplasia of the metacarpals, metatarsals, and phalanges. It is a clinically and genetically heterogeneous group of limb malformations. This study aimed to identify the pathogenic variant in a consanguineous Pakistani family with autosomal recessive SHFM. Peripheral blood samples were obtained, DNA was extracted, coding and noncoding regions were PCR amplified and Sanger sequencing was performed using workflow suggested by Thermo Fisher Scientific. A novel homozygous nonsense variant (c.1098C>A; p.Cys366*) was identified in the gene in the index patients, which probably explains SHFM type 6 in this family in comparison with similar data from the literature.

Background: Homozygous familial hypercholesterolemia (HoFH) is a severe form of familial hypercholesterolemia (FH), characterized by high low-density lipoprotein cholesterol (LDL-C) levels and increased coronary artery disease risk. This study reports a novel Alu insertion in the LDLR gene in a consanguineous Indian family, causing FH.
Objective: To identify and characterize the mutation causing HoFH in a proband and their family members.

Background: Diffuse hemispheric glioma, histone 3 (H3) G34-mutant, has been newly defined in the 2021 WHO classification of central nervous system tumors. Here we sought to define the prognostic roles of clinical, neuroimaging, pathological, and molecular features of these tumors.
Methods: We retrospectively assembled a cohort of 114 patients (median age 22 years) with diffuse hemispheric glioma, H3 G34-mutant, CNS WHO grade 4 and profiled the imaging, histological and molecular landscape of their tumors.

Fanconi anemia (FA) is a rare genetic disorder that affects multiple systems in the body and is the most prevalent congenital syndrome, leading to bone marrow failure. Twenty-two genes have been identified as contributors to the disease. Significant advancements have been made in the past 2 decades in understanding the genetic and pathophysiological processes involved.

Fragile X syndrome (FXS) presents with autism spectrum disorder (ASD), intellectual disability, developmental delay, seizures, hypotonia during infancy, joint laxity, behavioral issues, and characteristic facial features. The predominant mechanism is due to CGG trinucleotide repeat expansion of more than 200 repeats in the 5'UTR (untranslated region) of (Fragile X Messenger Ribonucleoprotein 1) causing promoter methylation and transcriptional silencing. However, not all patients presenting with the characteristic phenotype and point/frameshift mutations with deletions in have been described in the literature.

Introduction: Glycerol-3-phosphate dehydrogenase 1 (GPD1) deficiency is an autosomal recessive disorder causing hypertriglyceridemia, hepatomegaly, fatty liver, and hepatic fibrosis in infancy. It is an under-recognized cause of pediatric steatotic liver disease (SLD) with only 36 cases reported worldwide.
Method: We analyzed the clinical profile of our five cases diagnosed by exome sequencing (ES) and reviewed the published cases till December 2023 using PubMed search.
