Genetic Evidence of a Recent Decline and Crossbreed Distribution of TRPV4 c.1024G>T Variant in Domestic Cats. [PDF]
ABSTRACT The folded ear phenotype of Scottish Fold cats is associated with an autosomal dominant TRPV4 variant (c.1024G>T) linked to osteochondrodysplasia. Although genetic testing has been implemented to guide breeding, empirical evidence of its impact on allele frequency remains limited, and crossbreed investigations are lacking.

Novel Genetic Findings in Stuve-Wiedemann Syndrome: A Case Report and Review of Literature. [PDF]
ABSTRACT Stuve‐Wiedemann Syndrome (SWS) is a rare autosomal recessive condition, first reported in 1971 by Stuve and Wiedemann. It is associated with pathogenic or likely pathogenic homozygous or compound heterozygous variants in the Leukemia Inhibitory Factor Receptor (LIFR) gene.

Clinical Features of Seven COL2A1 Variations in Chinese Children With Type II Collagen Disorders. [PDF]
ABSTRACT Aim Type II collagen, encoded by the collagen type II alpha 1 (COL2A1) gene, is crucial for the structure of cartilage. This study aims to improve our understanding of Spondyloepiphyseal Dysplasia Congenita (SEDC) caused by mutations in COL2A1. We also aim to evaluate the safety and efficacy of growth hormone (GH) therapy in two SEDC patients.

Brachydactyly with Novel BMP8A and FGFR1 Variants: A Case Report with Review of Literature. [PDF]
The current study describes a novel type of brachydactyly, characterized by absent phalanges in the toes. Whole genome sequencing identified rare missense variants in the BMP8A and FGFR1 genes, both of which are known to play a role in bone development. Bioinformatic and protein network analysis support their involvement in bone deformities.
