Genes affected

UBAP1 (HGNC:12461): (ubiquitin associated protein 1) This gene is a member of the UBA domain family, whose members include proteins having connections to ubiquitin and the ubiquitination pathway. The ubiquitin associated domain is thought to be a non-covalent ubiquitin binding domain consisting of a compact three helix bundle. This particular protein originates from a gene locus in a refined region on chromosome 9 undergoing loss of heterozygosity in nasopharyngeal carcinoma (NPC). Taking into account its cytogenetic location, this UBA domain family member is being studies as a putative target for mutation in nasopharyngeal carcinomas. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.14223719).

BS1

Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.00000372 (5/1345738) while in subpopulation AFR AF= 0.000133 (4/30012). AF 95% confidence interval is 0.000045. There are 0 homozygotes in gnomad4_exome. There are 2 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 5 AD gene.

The c.394G>C (p.E132Q) alteration is located in exon 3 (coding exon 3) of the UBAP1 gene. This alteration results from a G to C substitution at nucleotide position 394, causing the glutamic acid (E) at amino acid position 132 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
