Genes affected
UBASH3A (HGNC:12462): (ubiquitin associated and SH3 domain containing A) This gene encodes one of two family members belonging to the T-cell ubiquitin ligand (TULA) family. Both family members can negatively regulate T-cell signaling. This family member can facilitate growth factor withdrawal-induced apoptosis in T cells, which may occur via its interaction with AIF, an apoptosis-inducing factor. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 30, 2024The c.278G>A (p.R93K) alteration is located in exon 3 (coding exon 3) of the UBASH3A gene. This alteration results from a G to A substitution at nucleotide position 278, causing the arginine (R) at amino acid position 93 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
