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]

Ambry Genetics

May 10, 2024

The c.507C>A (p.F169L) alteration is located in exon 3 (coding exon 3) of the LHX2 gene. This alteration results from a C to A substitution at nucleotide position 507, causing the phenylalanine (F) at amino acid position 169 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
