Pro49Ser) (NM_004187),其父母无该位点突变。根据美国医学遗传学与基因组学会(the American College of Medical Genetics and Genomics, ACMG)指南变异分类标准评定为可能致病性变异(PS2 + PM1 + PM2 + PP3)。结论:本病例KDM5C基因突变(c.145(exon 1)C>T, p.P49S(p. Pro49Ser)可能是X连锁精神发育迟滞-Claes-Jensen型综合征的致病性变异。基因检测有助于该病分子学诊断。展开更多

Mutations have been found in the ATRX gene in about one half of the patients. We report a typical clinical case. The clinical evidence leads us to continue the analysis of the gene despite a negative first screening. Indeed a new mutation was found, just behind the helicase domain, bringing up the interest of an effective collaboration between physicians and biologists.展开更多
