There are few words which are sometimes declined mistakenly in other declensions. But some of the shifts are not rare: a word pats besides sg. gen. paties is often said pačio and these two forms of sg. gen. are equal. Some words have parallel forms from other declensions with a little change in a meaning: dukra, dukros; sesė, sesės; palikuonis, -io, palikuonė, -ės. The forms sesė and dukra are more like unformal, than duktė, -ers and sesuo, -ers. For the word moteris the form motera were existent in dialects, but it is, differently from dukra, sesė cases, only a formal shift of declension without a meaning variation and such word would be perceived as a vernacularism and obsolete.
