Similar with 3/4 of my DC's.
DD's current diagnoses : GDD, Hypermobility, Speech & Language delay, dyspraxia, dyslexia, LD's, partial deafness, dyscalculia, 'Autistic traits' (trying to get a full dx now), Auditory Processing disorder, cardiac issues. And probably a few more I've forgotten...
She only had testing for Fragile X, which was ruled out.
DS2's current diagnoses : GDD, Speech & Language delay, Hypermobility syndrome, Auditory processing disorder, hypotonia, kyphosis, chronic brittle asthma, 'Autistic traits' (again, now trying to get a full dx).
He has only had testing for Fragile X, which was ruled out.
DS3's current diagnoses : GDD, Hypermobility, Speech & Language delay, hyperactivity 'with a high probability of ADHD', and he is being assessed for Autism in May. He also has multiple life threatening allergies.
Fragile X was ruled out, but he also had microarray testing which came back as 'nothing significant detected'. Though he does have worryingly high levels of an amino acid (Alanine) in his blood. Which may be indicative of mitochondrial disorders.
Whatever is wrong with one is wrong with all 3 IYSWIM.
I'm now leaning into researching mitochondrial disorders.
