Genes affected

TUFT1 (HGNC:12422): (tuftelin 1) Tuftelin is an acidic protein that is thought to play a role in dental enamel mineralization and is implicated in caries susceptibility. It is also thought to be involved with adaptation to hypoxia, mesenchymal stem cell function, and neurotrophin nerve growth factor mediated neuronal differentiation. [provided by RefSeq, Aug 2014]

The c.470G>A (p.S157N) alteration is located in exon 6 (coding exon 6) of the TUFT1 gene. This alteration results from a G to A substitution at nucleotide position 470, causing the serine (S) at amino acid position 157 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
