22 wrz 2009 · The 16p11.2 recurrent deletion involves the loss of one chromosome segment containing 25 annotated genes or transcripts [Kumar et al 2008, Marshall et al 2008, Weiss et al 2008]. The recurrent deletion is flanked by segmental duplications that contain four additional genes.
11 sty 2018 · The diagnosis of PRRT2-PxMD is established in a proband who has one of the following three findings on molecular genetic testing: a PRRT2 heterozygous pathogenic variant (~99% of affected individuals); the 16p11.2 recurrent deletion that includes PRRT2 (<1% of affected individuals); or biallelic PRRT2 pathogenic variants (<1% of affected ...
The 16p11.2 recurrent deletion is <i>de novo</i> in most probands. Less commonly, the deletion is transmitted from a parent to a child in an autosomal dominant manner. Once a 16p11.2 recurrent deletion has been identified in a family member, prenatal and preimplantation genetic testing are possible. ….
10 mar 2021 · 16p11.2 microdeletion is a known chromosomal anomaly associated mainly with neurocognitive developmental delay, predisposition to obesity, and variable dysmorphism.
9 paź 2023 · 16p11.2 deletion syndrome is a genetic disorder that is characterized by the deletion of a 593-kb region of chromosome 16 flanked by almost identical 147-kb segmental duplications subject to recurrent non-allelic recombination events [1].
Hearing loss. <11%. Both sensorineural & conductive reported. Paroxysmal kinesigenic dyskinesia (PKD) ≤9%. Incl benign familial infantile seizures, PKD, & PKD w/infantile convulsions. Cardiac malformations. 6%. From: 16p11.2 Recurrent Deletion.
15 cze 2020 · Overall, 16p11.2 CNVs have been categorized into 3 main syndromes: deletion of the proximal region (OMIM 611913), reciprocal duplication of the proximal region (OMIM 614671), and deletion of the distal region (OMIM 613444).
