We report on 2 brothers with short stature, microcephaly, myopia, retarded osseous maturation, severe developmental delay, and minor anomalies including temporal narrowing, periorbital fullness, full cheeks in infancy, and protruding lower lip. Both brothers and their parents had normal chromosomes. Fluorescence in situ hybridization with probes from all (sub-)telomeric chromosomal regions excluded a structural rearrangement involving telomeric segments. Because the pattern of congenital abnormalities is not like that of any well-known multiple congenital anomaly/mental retardation syndrome, we suggest a previously undescribed syndrome of autosomal recessive or X-linked inheritance.
我们报告了2名兄弟,他们身材矮小、小头畸形、近视、骨成熟延迟、严重发育迟缓,并伴有一些轻微异常,包括颞部狭窄、眶周饱满、婴儿期脸颊丰满以及下唇突出。兄弟俩及其父母的染色体均正常。使用来自所有(亚)端粒染色体区域的探针进行荧光原位杂交,排除了涉及端粒片段的结构重排。由于先天性异常模式与任何已知的多发性先天性异常/智力发育迟缓综合征均不相同,我们推测这是一种以前未描述过的常染色体隐性或X连锁遗传综合征。
