Genes affected

TBC1D1 (HGNC:11578): (TBC1 domain family member 1) TBC1D1 is the founding member of a family of proteins sharing a 180- to 200-amino acid TBC domain presumed to have a role in regulating cell growth and differentiation. These proteins share significant homology with TRE2 (USP6; MIM 604334), yeast Bub2, and CDC16 (MIM 603461) (White et al., 2000 [PubMed 10965142]).[supplied by OMIM, Mar 2008]

TBC1D1 Gene-Disease associations (from GenCC):

• non-syndromic renal or urinary tract malformation

  Inheritance: AD Classification: STRONG Submitted by: PanelApp Australia
• congenital anomaly of kidney and urinary tract

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BP7: Synonymous conserved (PhyloP=1.45 with no splicing effect.
