Genes affected

LHX5 (HGNC:14216): (LIM homeobox 5) 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 and be involved in the control of differentiation and development of the forebrain. In mice, this protein is essential for the regulation of precursor cell proliferation and the control of neuronal differentiation and migration during hippocampal development. This protein is involved in learning and motor functions in adult mice. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 07, 2021

The c.754T>C (p.F252L) alteration is located in exon 4 (coding exon 4) of the LHX5 gene. This alteration results from a T to C substitution at nucleotide position 754, causing the phenylalanine (F) at amino acid position 252 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
