Genes affected
LBX2 (HGNC:15525): (ladybird homeobox 2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in several processes, including muscle cell differentiation; positive regulation of convergent extension involved in gastrulation; and positive regulation of non-canonical Wnt signaling pathway. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.466G>A (p.E156K) alteration is located in exon 2 (coding exon 2) of the LBX2 gene. This alteration results from a G to A substitution at nucleotide position 466, causing the glutamic acid (E) at amino acid position 156 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
