Partial trisomy 3p/monosomy 9p with sex reversal

A female with XO/XY mosaicism and partial trisomy 9p.

A Case Report of 9p Deletion Syndrome Associated with Partial Trisomy of 1q42.

We report a case of partial deletion of 9p with partial trisomy of 1q42 syndrome, which is a rare clinical and cytogenetic report. The dysmorphic features of the patient include microcephaly, plagiocephaly, trigonocephaly with metopic ridge, arched eyebrows, hypertelorism, down-slanting palpebral fissure, ptosis, blepharophimosis, unilateral left epicanthic fold, long eyelashes, low-set and pos...

Partial Trisomy 9p(p22→pter) from a Maternal Translocation 4q35 and 9p22

We present clinical and cytogenetic data on a 7-year-old female child with partial trisomy for 9p22→9pter as a result of a maternal balanced reciprocal translocation. Her karyotype was ascertained as 46,XX,dec(4)t(4;9)(q35; p22)mat. The father had a normal karyotype, while the mother had an apparently balanced translocation involving chromosomes 4 and 9 [46,XX,t(4;9)(q35;p22)]. This case will b...

Familial 'partial 9p' trisomy: six cases and four carriers in three generations.

Six cases of translocation trisomy for the distal half of the short arm of a number 9 chromosome and four asymptomatic balanced translocation carriers are presented in a three-generation pedigree. The clinical features are remarkably similar to those recently recognized and increasingly reported in full short arm (9p) trisomy and should be considered a modification of the same syndrome. In addi...

Oropharyngeal dysphagia and language delay in partial trisomy 9p: case report.

The phenotype of partial trisomy 9p includes global developmental delay, microcephaly, bulbous nose, downturned oral commissures, malformed ears, hypotonia, and severe cognitive and language disorders. We present a case report and a comparative review of clinical findings on this condition, focusing on speech-language development, cognitive abilities and swallowing evaluation. We suggest that o...
