Genetic Variant SCLY:p.Met50Ile (chr2-238064417-G-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_016510.7(SCLY):c.150G>T(p.Met50Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,611,716 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M50T) has been classified as Uncertain significance.

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]

SCLY links:

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]
