Genes affected

SNIP1 (HGNC:30587): (Smad nuclear interacting protein 1) This gene encodes a protein that contains a coiled-coil motif and C-terminal forkhead-associated (FHA) domain. The encoded protein functions as a transcriptional coactivator that increases c-Myc activity and inhibits transforming growth factor beta (TGF-beta) and nuclear factor kappa-B (NF-kB) signaling. The encoded protein also regulates the stability of cyclin D1 mRNA, and may play a role in cell proliferation and cancer progression. Mutations in this gene are a cause of psychomotor retardation, epilepsy, and craniofacial dysmorphism (PMRED). [provided by RefSeq, Mar 2012]

The c.1153G>A (p.E385K) alteration is located in exon 4 (coding exon 4) of the SNIP1 gene. This alteration results from a G to A substitution at nucleotide position 1153, causing the glutamic acid (E) at amino acid position 385 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with SNIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 385 of the SNIP1 protein (p.Glu385Lys). -
