Genes affected

UNCX (HGNC:33194): (UNC homeobox) This gene encodes a homeobox transcription factor that is involved in somitogenesis and neurogenesis and is required for the maintenance and differentiation of specific elements of the axial skeleton. This gene also plays a role in controlling the development of connections of hypothalamic neurons to pituitary elements, allowing central neurons to reach the peripheral blood circulation and deliver hormones that control peripheral functions. The expression of this gene is associated with an increased frequency of acute myeloid leukemia. [provided by RefSeq, Jul 2017]

Collection Method: clinical testing

The c.299G>C (p.S100T) alteration is located in exon 2 (coding exon 2) of the UNCX gene. This alteration results from a G to C substitution at nucleotide position 299, causing the serine (S) at amino acid position 100 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
