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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 03, 2022 | The c.775A>T (p.N259Y) alteration is located in exon 8 (coding exon 7) of the SEPHS1 gene. This alteration results from a A to T substitution at nucleotide position 775, causing the asparagine (N) at amino acid position 259 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
