Genes affected

LHX6 (HGNC:21735): (LIM homeobox 6) This gene encodes a member of a large protein family that contains the LIM domain, a unique cysteine-rich zinc-binding domain. The encoded protein has tandem LIM domains as well as a DNA-binding homeodomain. The protein functions as a transcription factor involved in embryogenesis and head development and is highly expressed in neural crest derived mesenchyme cells. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jan 2017]

Dec 21, 2023

The c.67G>A (p.G23S) alteration is located in exon 1 (coding exon 1) of the LHX6 gene. This alteration results from a G to A substitution at nucleotide position 67, causing the glycine (G) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
