Genes affected

UBA1 (HGNC:12469): (ubiquitin like modifier activating enzyme 1) The protein encoded by this gene catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation. This gene complements an X-linked mouse temperature-sensitive defect in DNA synthesis, and thus may function in DNA repair. It is part of a gene cluster on chromosome Xp11.23. Alternatively spliced transcript variants that encode the same protein have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM1

In a mutagenesis_site Localizes to the cytoplasm. (size 65) in uniprot entity UBA1_HUMAN there are 6 pathogenic changes around while only 1 benign (86%) in ENST00000335972.11

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), UBA1. . Gene score misZ 3.4752 (greater than the threshold 3.09). GenCC has associacion of gene with infantile-onset X-linked spinal muscular atrophy, inflammatory disease.

BP4

Computational evidence support a benign effect (MetaRNN=0.13601017).
