| [Deletions of the terminal portion of the short arm of chromosome 9 are associated with ID due to DOCK8 haploinsufficiency [34, 35] and a male to female sex] reversal, possibly due to DMRT1 and DMRT2 haploinsufficiency [23]. Although in female patients no urogenital anomalies are reported, we cannot completely rule out the hypothesis that the mild abnormal morphology of the uterus reported in our patient could be due to haploinsufficiency of the 9p region. Therefore, more accurate gynaecologic evaluation in the proband could be useful.
The rearrangements present in our patients originated from a balanced translocation present in a parent as demonstrated by FISH analysis. In family 2, the mother presented isolated microcephaly with normal intellectual functioning, and experienced two spontaneous miscarriages in the first month of gestation. In addition, the family history revealed that, two maternal cousins of the proband suffered from psychomotor delay. All these data indicated a segregation of the translocation in the maternal branch of the family.

Deletions of the terminal portion of the short arm of chromosome 9 are associated with a male to female sex reversal, possibly due to DMRT1 and DMRT2 haploinsufficiency [Barbaro et al. 2009]. [...] Although in female patients no urogenital anomalies are reported, we cannot completely rule out the hypothesis that the mild abnormal morphology of the uterus reported in our patient could be due to haploinsufficiency of the 9p region. We therefore planned an accurate gynecologic evaluation in the proband.
The rearrangement present in our case is originated by a balanced translocation present in the mother as demonstrated by FISH analysis. The mother presents isolated microcephaly with normal psychomotor development and mental abilities and experienced two spontaneous abortions in the first month of gestation. In addition, from the family history, two maternal cousins of the proband are referred to suffer from psychomotor delay. All this data indicate a segregation of the translocation in the maternal branch of the family. |
Nothing has been marked as a citation. The original text is part of an article which is included in Katzaki's thesis. The patient described here is obviously the same (albeit now several years older). Mmu was not one of the coauthors of the original article. There is no hint given that this description is not Mmu's own. Neither is there a hint given that this patient's genetic material has been analyzed in a different context before. The take-over from the original text is continued in Mmu/Fragment_037_20. The reference for [Barbaro et al. 2009] is missing in Katzaki (2009). |
