Genes affected

UPK3A (HGNC:12580): (uroplakin 3A) This gene encodes a member of the uroplakin family, a group of transmembrane proteins that form complexes on the apical surface of the bladder epithelium. Mutations in this gene may be associated with renal adysplasia. Alternatively spliced transcript variants have been described.[provided by RefSeq, Nov 2009]

UPK3A Gene-Disease associations (from GenCC):

• renal agenesis, unilateral

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• renal dysplasia

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics
• congenital anomaly of kidney and urinary tract

  Inheritance: AD Classification: NO_KNOWN Submitted by: ClinGen

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.819
