Genes affected

NHS (HGNC:7820): (NHS actin remodeling regulator) This gene encodes a protein containing four conserved nuclear localization signals. The encoded protein functions in eye, tooth, craniofacial and brain development, and it can regulate actin remodeling and cell morphology. Mutations in this gene have been shown to cause Nance-Horan syndrome, and also X-linked cataract-40. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, May 2014]

The c.49C>T (p.R17W) alteration is located in exon 1 (coding exon 1) of the NHS gene. This alteration results from a C to T substitution at nucleotide position 49, causing the arginine (R) at amino acid position 17 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
