過去に報告のない,9 番染色体長腕部分トリソミー,X 染色体長腕部分モノソミー(partial trisomy 9q and partial
monosomy Xq)の女児を経験した。在胎40 週,2,382g で出生し,長い手足,くも状指,関節拘縮,特異な顔貌が
認められた。日齢5 に胃破裂を発症し緊急開腹術を行い,1 歳3 か月時に上気道狭窄に対して気管切開術を行った。
長い手足やくも状指はMarfan 症候群を想起させるが,partial trisomy 9q の特徴の一つでもあり,診断にあたって
はMarfan 症候群との鑑別が重要と考えられた。Partial trisomy 9q では,過去に胃破裂の報告はないが幽門狭窄の
合併が知られており,上部消化管通過障害に留意すべきである。また,経過中に上気道狭窄症状が進行する場合が
ある。Partial monosomy Xq では二次性徴の異常をきたす可能性がある。 |

We experienced a novel case of partial trisomy 9q and partial monosomy Xq not previously reported. A female infant
was born at 40 gestational weeks with a birth weight of 2,382g, elongated arms and legs, arachnodactyly, joint contracture,
and a distinctive face. At 5 days of age, she underwent an emergency laparotomy for gastric rupture, and had a tracheotomy
at the age of 15 months. Although physical findings such as long arms and legs or arachnodactyly are often associated
with Marfan’s syndrome, they can also be indicative of partial trisomy 9q, and therefore diagnostic differentiation is critical.
Pyloric stenosis due to partial trisomy 9q has been previously reported, but to the best of our knowledge, this is the
first case associated with gastric rupture. Therefore, we recommend that clinicians evaluate and closely monitor gastrointestinal
transit in cases of suspected partial trisomy 9q. Narrowing of the upper airway may progress during the course.
Partial monosomy Xq may cause abnormal secondary sexual characteristics. |
