Genes affected

NOMO3 (HGNC:25242): (NODAL modulator 3) This gene encodes a protein originally thought to be related to the collagenase gene family. This gene is one of three highly similar genes in a duplicated region on the short arm of chromosome 16. These three genes encode closely related proteins that may have the same function. The protein encoded by one of these genes has been identified as part of a protein complex that participates in the Nodal signaling pathway during vertebrate development. Mutations in ABCC6, which is located nearby, rather than mutations in this gene are associated with pseudoxanthoma elasticum. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.7G>C (p.V3L) alteration is located in exon 1 (coding exon 1) of the NOMO3 gene. This alteration results from a G to C substitution at nucleotide position 7, causing the valine (V) at amino acid position 3 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
