Genes affected

EN1 (HGNC:3342): (engrailed homeobox 1) Homeobox-containing genes are thought to have a role in controlling development. In Drosophila, the 'engrailed' (en) gene plays an important role during development in segmentation, where it is required for the formation of posterior compartments. Different mutations in the mouse homologs, En1 and En2, produced different developmental defects that frequently are lethal. The human engrailed homologs 1 and 2 encode homeodomain-containing proteins and have been implicated in the control of pattern formation during development of the central nervous system.

The c.701G>T (p.S234I) alteration is located in exon 1 (coding exon 1) of the EN1 gene. This alteration results from a G to T substitution at nucleotide position 701, causing the serine (S) at amino acid position 234 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
