Remarks Clinically affected; milder neurological phenotype than classic A-T; normal childhood development; examination at 9.5 years of age: mild bilateral conjunctival telangiectasia, normal gait, ability to hop on one foot, no nystagmus, no dysmetria, no choreoathetosis, some tendency to sway while sitting, difficulty standing in one position with feet together, difficulty with tandem gait, mild dysarthria, tendency for drooling, disdiadochokinesis, and difficulty with handwriting; no history of sinopulmonary infections; elevated serum alpha fetoprotein (92.5 ng/ml, normal ref value is 0-15 ng/ml) and low levels of IgG4 (<0.01 g/L, normal ref value is 0.11-1.57 g/L); brain MRI revealed enlargement of the 4th ventricle and atrophy of the vermis; A-T Neurological Index Score (91, Z=4.31); no ATM was detected in the donor's cells and Mre11 levels were normal; donor subject is homozygous for a 1 bp deletion at nucleotide 5653 in exon 39 of the ATM gene (5653delA) resulting in a frameshift at codon 1885 leading to truncation at codon 1915; consanguineous family; affected brother is GM22961(fibroblast)/GM22963(B-lymphocyte); see GM22692 for donor’s lymphoblast line; for more information, refer to Patient V6 in publication by Alterman et al (PMID: 17632790).
