Age at attaining sitting without support and walking with or without support in 24 patients with LAMA2‐RD. Tick marks on vertical axis indicate single patients. Patients with more severe phenotype/complete merosin deficiency (CD) are included in bottom section; patients with milder phenotype/partial deficiency (PD) are in the top section. Dots: age at independent sitting. Squares: age at walking with support. Triangle: age at independent walking. The continuous vertical line at 9 months and dashed line at 18 months indicates WHO thresholds for attaining independent sitting and walking alone in 99% of children, respectively (reference: WHO Multicentre Growth Reference Study Group. WHO Motor Development Study: Windows of achievement for six gross motor development milestones. Acta Paediatrica Supplement 2006;450:86‐95).
