Genes affected
SCLY (HGNC:18161): (selenocysteine lyase) Selenocysteine lyase (SCLY; EC 4.4.1.16) catalyzes the pyridoxal 5-prime phosphate-dependent conversion of L-selenocysteine to L-alanine and elemental selenium (Mihara et al., 2000 [PubMed 10692412]).[supplied by OMIM, Mar 2008]
UBE2F-SCLY (HGNC:48339): (UBE2F-SCLY readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring UBE2F (ubiquitin-conjugating enzyme E2F) and SCLY (selenocysteine lyase) genes on chromosome 2. The read-through transcript is a candidate for non-sense mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.230G>T (p.R77I) alteration is located in exon 3 (coding exon 3) of the SCLY gene. This alteration results from a G to T substitution at nucleotide position 230, causing the arginine (R) at amino acid position 77 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
