| Remarks |
Clinically affected; anthropometric measurements at age 84.9 years: height = 130 cm, height SD score = -5.5, upper to lower segment ratio = 1.3, upper to lower segment z-score = 13.7, arm span = 105.3 cm, arm span z-score = -7.9, right tibial length z-score = -5.7, right radial length z-score = -6.3, fourth metacarpal z-score = -2.3; menarche at age 13 years; high arched palate; normal fingernails; no scoliosis; marked increased carrying angle; severe mesomelia; marked ulnar hypoplasia; hypoplastic fibulae; severe Madelung wrist deformity; fused epiphyses; donor subject is a compound heterozygote: one allele has a C>T transition at nucleotide 457 in exon 3 of the SHOX gene [457C>T] resulting in a substitution of cysteine for arginine at codon 153 [Arg153Cys (R153C)] and a second allele has a G>T transversion at nucleotide 487 in exon 4 of the SHOX gene [487G>T] resulting in a substitution of phenylalanine for valine at codon 163 [Val163Phe (V163F)]; subject's mother reportedly had short stature (152 cm) and short arms and father reportedly had normal stature (178 cm) and short arms. |
