Genes affected

GSS (HGNC:4624): (glutathione synthetase) Glutathione is important for a variety of biological functions, including protection of cells from oxidative damage by free radicals, detoxification of xenobiotics, and membrane transport. The protein encoded by this gene functions as a homodimer to catalyze the second step of glutathione biosynthesis, which is the ATP-dependent conversion of gamma-L-glutamyl-L-cysteine to glutathione. Defects in this gene are a cause of glutathione synthetase deficiency. [provided by RefSeq, Jul 2008]

GSS Gene-Disease associations (from GenCC):

• inherited glutathione synthetase deficiency

  Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
• glutathione synthetase deficiency with 5-oxoprolinuria

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
