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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.820G>A (p.D274N) alteration is located in exon 2 (coding exon 2) of the LBX1 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the aspartic acid (D) at amino acid position 274 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
