Genes affected

LHX2 (HGNC:6594): (LIM homeobox 2) This gene encodes a protein belonging to a large protein family, members of which carry the LIM domain, a unique cysteine-rich zinc-binding domain. The encoded protein may function as a transcriptional regulator. The protein can recapitulate or rescue phenotypes in Drosophila caused by a related protein, suggesting conservation of function during evolution. [provided by RefSeq, Jul 2008]

Feb 17, 2023

The c.61A>G (p.R21G) alteration is located in exon 1 (coding exon 1) of the LHX2 gene. This alteration results from a A to G substitution at nucleotide position 61, causing the arginine (R) at amino acid position 21 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
