Any Good Resources For Folks With Chromosome 16p11.2 Duplication Or Parents With Children With This Genetic Variation?

I just found out that my 19 month old has this variation (through a chromosome microarray). There seems to be more information related to 16p11.2 deletion over the duplication. Anyone else's child have this? Can I hear from your experiences? We are slated to see a geneticist in September. Thanks in advance!
