Genetic Variant NOMO1:p.Glu321Gly (chr16-14854025-A-G) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4

The NM_014287.4(NOMO1):c.962A>G(p.Glu321Gly) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E321K) has been classified as Uncertain significance.

Genes affected

NOMO1 (HGNC:30060): (NODAL modulator 1) 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 region of duplication located on the p 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 (PXE). [provided by RefSeq, Jul 2008]

The c.962A>G (p.E321G) alteration is located in exon 9 (coding exon 9) of the NOMO1 gene. This alteration results from a A to G substitution at nucleotide position 962, causing the glutamic acid (E) at amino acid position 321 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
