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]

The c.226C>T (p.P76S) alteration is located in exon 2 (coding exon 2) of the LBX2 gene. This alteration results from a C to T substitution at nucleotide position 226, causing the proline (P) at amino acid position 76 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
