Genes affected

LBX1 (HGNC:16960): (ladybird homeobox 1) This gene and the orthologous mouse gene were found by their homology to the Drosophila lady bird early and late homeobox genes. In the mouse, this gene is a key regulator of muscle precursor cell migration and is required for the acquisition of dorsal identities of forelimb muscles. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 04, 2022

The c.226C>T (p.R76C) alteration is located in exon 1 (coding exon 1) of the LBX1 gene. This alteration results from a C to T substitution at nucleotide position 226, causing the arginine (R) at amino acid position 76 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
