Genes affected

FLRT2 (HGNC:3761): (fibronectin leucine rich transmembrane protein 2) This gene encodes a member of the fibronectin leucine rich transmembrane (FLRT) family of cell adhesion molecules, which regulate early embryonic vascular and neural development. The encoded type I transmembrane protein has an extracellular region consisting of an N-terminal leucine-rich repeat domain and a type 3 fibronectin domain, followed by a transmembrane domain and a short C-terminal cytoplasmic tail domain. It functions as both a homophilic cell adhesion molecule and a heterophilic chemorepellent through its interaction with members of the uncoordinated-5 receptor family. Proteolytic removal of the extracellular region controls the migration of neurons in the developing cortex. Alternative splicing results in multiple transcript variants.

Mar 01, 2023

The c.596C>T (p.A199V) alteration is located in exon 2 (coding exon 1) of the FLRT2 gene. This alteration results from a C to T substitution at nucleotide position 596, causing the alanine (A) at amino acid position 199 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
