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]

Sep 29, 2023

The c.704C>T (p.A235V) alteration is located in exon 3 (coding exon 3) of the LHX2 gene. This alteration results from a C to T substitution at nucleotide position 704, causing the alanine (A) at amino acid position 235 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
