Novel Homozygous LAMC3 Frameshift Variant Associated with Confluent Leukoencephalopathy and Low-Grade Tectal Glioneuronal Tumor: Expanding the Phenotypic Spectrum with Bioinformatic Characterization
Background: Biallelic loss-of-function variants in LAMC3, encoding laminin gamma-3, cause occipital cortical malformation (OMIM#614115). White matter disease and intracranial neoplasia have not been reported in this spectrum. We report a novel homozygous LAMC3 frameshift variant, expanding its phenotypic and molecular...
