Genes affected
SGTA (HGNC:10819): (small glutamine rich tetratricopeptide repeat co-chaperone alpha) This gene encodes a protein which is capable of interacting with the major nonstructural protein of parvovirus H-1 and 70-kDa heat shock cognate protein; however, its function is not known. Since this transcript is expressed ubiquitously in various tissues, this protein may serve a housekeeping function. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.323A>G (p.E108G) alteration is located in exon 5 (coding exon 4) of the SGTA gene. This alteration results from a A to G substitution at nucleotide position 323, causing the glutamic acid (E) at amino acid position 108 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
