| Remarks |
Clinically affected; foreskin; type II lissencephaly; congenital myotonic dystrophy; hydrocephalus indicated in utero by MRI; no aqueductal stenosis by post-natal MRI/CT; vermis hypoplasia; absent septum pellucidum; CPK = 2,200 u/ml; retinal exam showed vitreous hemorrhage but no pigmentary retinopathy; hypertonia; karyotype is 46,XY.ish 17(LIS1x2,RARAx2); donor is a compound heterozygote: one allele has a 1 bp deletion at nucleotide 385 in exon 5 of the FKTN gene (c.385delA) resulting in a frameshift and creation of a stop at codon 129 (I129fsX1); the second allele has a C>A transversion at nucleotide 1176 in exon 10 (c.1176C>A) resulting in a stop at codon 392 [Tyr392Ter (Y392X)] |
