Green List (high evidence)

The UBA1 gene is associated with both AR & somatic conditions (OMIM).

For carrier screening testing, the only relevant condition is AR Spinal muscular atrophy, X-linked 2, infantile MIM#301830 (XL-SMA).

XL-SMA is characterised by neonatal onset of severe hypotonia, areflexia, and multiple congenital contractures (arthrogryposis), associated with loss of anterior horn cells and infantile death. More than 10 families reported, functional data. Death usually in infancy due to respiratory failure. Increased spontaneous abortions in carrier mothers (OMIM).

Genotype-phenotype correlation (PMID: 39762237): The mutations identified in SMAX2 patients are located exclusively in exon 15, those identified in VEXAS are outside of the SMAX2 mutation hotspot. However, the principle of the genotype-phenotype correlation remains unclear. No truncation mutation or whole gene deletion have been identified, suggesting that a complete loss of UBA1 activity may be embryonically lethal.
