Genes affected

SEPHS1 (HGNC:19685): (selenophosphate synthetase 1) This gene encodes an enzyme that synthesizes selenophosphate from selenide and ATP. Selenophosphate is the selenium donor used to synthesize selenocysteine, which is co-translationally incorporated into selenoproteins at in-frame UGA codons. [provided by RefSeq, Sep 2010]

The c.931G>A (p.G311S) alteration is located in exon 8 (coding exon 7) of the SEPHS1 gene. This alteration results from a G to A substitution at nucleotide position 931, causing the glycine (G) at amino acid position 311 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
