Genes affected

SUCLG2 (HGNC:11450): (succinate-CoA ligase GDP-forming subunit beta) This gene encodes a GTP-specific beta subunit of succinyl-CoA synthetase. Succinyl-CoA synthetase catalyzes the reversible reaction involving the formation of succinyl-CoA and succinate. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 5 and 12. [provided by RefSeq, Apr 2010]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1150G>A (p.E384K) alteration is located in exon 10 (coding exon 10) of the SUCLG2 gene. This alteration results from a G to A substitution at nucleotide position 1150, causing the glutamic acid (E) at amino acid position 384 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 384 of the SUCLG2 protein (p.Glu384Lys). This variant is present in population databases (rs199589191, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with SUCLG2-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
