Of the 8 affected children that have thus far been reported, none had gastrointestinal symptoms or severe liver dysfunction. Two had bilateral cataracts. All had normal growth and development (summary by Wada et al., 2019).&#13; For a discussion of genetic heterogeneity of galactosemia, see GALAC1 (230400). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>
