Optical Genome Mapping Identifies a Second Xq27.1 Rearrangement Associated With Charcot–Marie–Tooth Neuropathy CMTX3

Abstract excerpt

BACKGROUND: X-linked recessive type 3 Charcot-Marie-Tooth (CMTX3) is a rare subtype of childhood-onset CMT. To date, all reported CMTX3 patients share a common founder 78 kb insertion from chromosome 8 into the Xq27.1 palindrome region. METHODS: We conducted patient-parent trio optical genome mapping (OGM) on a male patient presenting with clinically diagnosed Dejerine-Sottas disease for whom initial standard...
