Height, arm span and leg length develop far below normal population ranges. We present growth and body proportion charts for ages 0\u201320\u2009years, constructed from semi\u2010longitudinal standardized measurements of about 450 children, along with some examples of achondroplasia typical and atypical growth pattern. We combine head circumference, height and weight for 0\u20134\u2009years into one (infancy) page and height and weight for 4\u201320\u2009years in another (childhood\u2013adolescence) using nonlinear axes to account for the rapidly decreasing growth velocity. Similarly, weight and BMI are based on nonlinear axes to balance wide SD\u2010channels at higher and narrow SD\u2010channels at lower levels of weight\/BMI. Charts for following sitting height, sitting height\/height ratio, arm span, leg and foot length are also presented. Clinical examples illustrating the applicability of the charts include cases of extreme prematurity, extreme head circumference development before and after shunting, achondroplasia complicated by chromosomal or additional genetic abnormality and by growth hormone deficiency as well as of evaluating growth promoting therapy.<\/jats:p>","DOI":"10.1002\/ajmg.a.61974","type":"journal-article","created":{"date-parts":[[2020,11,21]],"date-time":"2020-11-21T13:11:54Z","timestamp":1605964314000},"page":"401-412","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Clinical charts for surveillance of growth and body proportion development in achondroplasia and examples of their use"],"prefix":"10.1002","volume":"185","author":[{"given":"Luitgard","family":"Neumeyer","sequence":"first","affiliation":[{"name":"Pediatric Endocrinology Unit, Karolinska University Hospital Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Merker","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5605-2462","authenticated-orcid":false,"given":"Lars","family":"Hagen\u00e4s","sequence":"additional","affiliation":[{"name":"Pediatric Endocrinology Unit, Karolinska University Hospital Stockholm Sweden"},{"name":"Department of Women's and Children's Health Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,11,21]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1515\/jpem-2016-0362"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph7031047"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0258(19980228)17:4<407::AID-SIM742>3.0.CO;2-L"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.4780111005"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2047-6310.2012.00064.x"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/03014460110085331"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdra.20653"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.2471\/BLT.07.043497"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1515\/jpem-2017-0471"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.61120"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.5546\/aap.2017.eng.234"},{"key":"e_1_2_9_13_1","volume-title":"Endocrine Medicine \u2013 Volume 1: General considerations","author":"Engelbach W.","year":"1932"},{"issue":"35","key":"e_1_2_9_14_1","first-page":"2960","article-title":"Growth diagrams for height, weight and head circumference from birth to the age of 18\u2009years","volume":"29","author":"Engstrom I.","year":"1973","journal-title":"L\u00e4kartidningen"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004703-199706000-00001"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-004-1586-7"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2004.050799"},{"key":"e_1_2_9_18_1","volume-title":"Pediatric morphometrics \u2013 A reference manual","author":"Gerver W.","year":"2011"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004310000706"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31873"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.38150"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/88.2.364"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(78)81152-4"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19960329)62:3<255::AID-AJMG10>3.0.CO;2-J"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19960301)62:1<91::AID-AJMG18>3.0.CO;2-Q"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.2012.04234.x"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1097\/DBP.0b013e3181c72052"},{"key":"e_1_2_9_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2605.2005.00556.x"},{"key":"e_1_2_9_29_1","doi-asserted-by":"publisher","DOI":"10.1080\/08035250152708851"},{"key":"e_1_2_9_30_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.113.6.e617"},{"key":"e_1_2_9_31_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.40356"},{"key":"e_1_2_9_32_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.38853"},{"issue":"116","key":"e_1_2_9_33_1","first-page":"8","article-title":"Skeletal growth and development of the achondroplastic dwarf","author":"Nehme A.
