Association between
i. Deafmutism ii. Blindness iii. imbecility – do you mean in relation to albinism or what? – I have not read what there is in Biometrika on D-Mism; I do not see mention of the complications ii. & iii. in Treasury, but have not looked at individual pedigrees. Assocn. between D.mism, Idiocy & Retinitis pigmentosa is of course an old story though the relative frequencies of the 3 conditions or the degree in which they may act as equivalents to each other, substitutes I mean, has never been worked out. If you have data to work that out you will be doing a much wanted piece of work. It is just mentioned in a paper by E.N. lately pubd. of which you have a copy.
I did not know that D-Mism & congent. Idiocy were often associated with other kinds of blindness, except the relatively small claim of “tower-skull”. But I may likely enough be wrong.
