Honestly, I haven't been following any newer developments in these fields for a while. In fact, whenever I see Ryan and Allora, I ask them what's new in the area as they work in a related field. I'm sure Naomi can also talk more about recent developments. But, your question is one reason why they need genetic samples from affecteds and non-affecteds to compare their genomes and see if there are any anomalies that differ and that could be related to these expressions of SB and/or clefts. I haven't looked up any literature about human clefts and the differences between a nutritional deficiency affected versus an inherited affected.
