POLR1C thiab POLR1D yog ib qho ntxiv 2% ntawm cov neeg mob. Hauv cov tib neeg uas tsis muaj kev hloov pauv tshwj xeeb hauv ib qho ntawm cov noob, qhov ua rau tus kab mob tsis paub.

Lawv koom nrog hauv kev tsim cov molecule hu ua ribosomal RNA (rRNA), cov tshuaj lom neeg ntawm DNA. Ribosomal RNA pab sib sau cov protein blocks (amino acids) rau hauv cov proteins tshiab, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm tes thiab muaj sia nyob. Kev hloov pauv hauv TCOF1, POLR1C, lossis POLR1D cov noob txo qis rRNA ntau lawm. Cov kws tshawb fawb ntseeg tias qhov txo qis ntawm rRNA tuaj yeem ua rau kev puas tsuaj rau tus kheej ntawm qee lub hlwb koom nrog kev tsim cov pob txha ntawm lub ntsej muag thiab cov ntaub so ntswg.

Hauv lwm qhov xwm txheej, tus mob no tau txais los ntawm cov noob hloov pauv los ntawm niam txiv.

Thaum tus kab mob tshwm sim los ntawm kev hloov pauv hauv cov noob POLR1C, nws raug suav tias yog hom autosomal recessive ntawm qub txeeg qub teg. Ib tug niam txivTus kab mob autosomal recessive muaj ib daim qauv ntawm cov noob hloov pauv, tab sis lawv feem ntau tsis pom cov tsos mob thiab cov tsos mob ntawm tus kab mob.
