Genes affected

DMXL1 (HGNC:2937): (Dmx like 1) The protein encoded by this gene is a member of the WD repeat superfamily of proteins, which have regulatory functions. This gene is expressed in many tissue types including several types of eye tissue, and it has been associated with ocular phenotypes. In addition, it is upregulated in cultured cells that overexpress growth factor independence 1B, a transcription factor that is essential for hematopoietic cell development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

The c.335T>C (p.I112T) alteration is located in exon 4 (coding exon 4) of the DMXL1 gene. This alteration results from a T to C substitution at nucleotide position 335, causing the isoleucine (I) at amino acid position 112 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
