Genes affected
GSTK1 (HGNC:16906): (glutathione S-transferase kappa 1) This gene encodes a member of the kappa class of the glutathione transferase superfamily of enzymes that function in cellular detoxification. The encoded protein is localized to the peroxisome and catalyzes the conjugation of glutathione to a wide range of hydrophobic substates facilitating the removal of these compounds from cells. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2009]
TMEM139-AS1 (HGNC:40988): (TMEM139 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.313G>A (p.A105T) alteration is located in exon 4 (coding exon 4) of the GSTK1 gene. This alteration results from a G to A substitution at nucleotide position 313, causing the alanine (A) at amino acid position 105 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
