ADTKD MUC1

An inherited disorder that causes a gradual loss of kidney function, caused by a mutation in the MUC1 gene that leads to production of an abnormal mucin 1 protein, which deposits in the kidney and leads to slow loss of kidney function¹.

Prevalence

2.5 1,000,000

Disease is affected 1-4/1,000,000 (likely an underestimate due to unremarkable findings); repeat expansion responsibile for 95% of disease²

Age of Onset Details

Age of onset for end-stage renal disease (the only systemic manifestation) ranges from 16³-70².

Details

Disease is caused by the single base expansion of a heptanucleotide (7) cytosine homopolymer tract (i.e. from (C)7 to (C)8 ) within one copy of a coding VNTR, resulting in a frameshift mutation. This VNTR has a 60 bp motif, varying in length and sequence composition. This motif ranges in copy number from 20-125 (~1.5-5 kb) and is GC-rich (>80%). The specific copy of the VNTR motif involved varies by family but is consistent within a family⁴. This locus is particularly difficult to genotype^5,6. Gamaarachchi et al. observed 20 unique VNTR haplotypes which ranged in size from 40–83 copies, with no unrelated individuals sharing the same haplotype. Unique haplotypes implied frequent independent origins of the dupC variant⁷. NOTE: Disease is caused by a 7 to 8 C homopolymer expansion within the main motif which we represent here as a change in motif.
