Finally, we found 20 known deafness genes enriched in supporting cells at P1 (Tmprss3, Cabp2, Ush1c, Ildr1, Otog, Smp, Pou4f3, Gipc3, Grxcr2, Grhl2, Otof, Loxhd1, Strc, Grxcr1, Myo3a, Ptprq, Myh14, Marveld2, Pcdh15 and Fam65b), 18 enriched at P6 (Tmprss3, Smpx, Otog, P2rx2, Ildr1, Strc, Loxhd1, Ush1c, Pou4f3, Slc26a5, Grxcr2, Pcdh15, Grhl2, Otof, Ceacam16, Tmc1, Marveld2 and Gjb6) and just five changing significantly between P1 to P6 (Ceacam16, Tnc, Otoa, Slc26a5 and P2rx2). Here, PTPRQ is linked to deafness.
