Genes affected

ESX1 (HGNC:14865): (ESX homeobox 1) This gene encodes a dual-function 65 kDa protein that undergoes proteolytic cleavage to produce a 45 kDa N-terminal fragment with a paired-like homeodomain and a 20 kDa C-terminal fragment with a proline-rich domain. The C-terminal fragment localizes to the cytoplasm while the N-terminal fragment localizes exclusively to the nucleus. In contrast to human, the mouse homolog has a novel PN/PF motif in the C-terminus and is paternally imprinted in placental tissue. This gene likely plays a role in placental development and spermatogenesis. [provided by RefSeq, Jan 2010]

The c.988G>C (p.V330L) alteration is located in exon 4 (coding exon 4) of the ESX1 gene. This alteration results from a G to C substitution at nucleotide position 988, causing the valine (V) at amino acid position 330 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
