Description

In 3 children with intrauterine growth retardation, cutis laxa, hip dislocation, hernias, osteopenia, and mental retardation (ARCL2B; 612940) from 2 unrelated consanguineous Kuwaiti families, originally reported by Nanda et al. (2008), Reversade et al. (2009) identified homozygosity for a 797G-A transition in exon 6 of the PYCR1 gene, resulting in an arg266-to-gln (R266Q) substitution predicted to affect splicing by altering the invariable donor splice site at the 3-prime end of exon 6.
