Malformations of cortical development v7.39 ISCA-46300-Loss Arina Puzriakova Region: isca-46300-loss has been classified as Green List (High Evidence).
Malformations of cortical development v7.38 ISCA-46300-Loss Arina Puzriakova Tag Q3_25_promote_green was removed from Region: ISCA-46300-Loss.
Malformations of cortical development v7.38 ISCA-46300-Loss Arina Puzriakova commented on Region: ISCA-46300-Loss: The rating of this region has been updated to Green following NHS Genomic Medicine Service approval.
Malformations of cortical development v7.16 ISCA-46300-Loss Arina Puzriakova Classified Region: ISCA-46300-Loss as Amber List (moderate evidence)
Malformations of cortical development v7.16 ISCA-46300-Loss Arina Puzriakova Added comment: Comment on list classification: This region has Sufficient Evidence for Haploinsufficiency in ClinGen and should be promoted to Green at the next GMS panel update.

Panel inclusion has been reviewed and approved by the Genomics England Clinical team.

Malformations of cortical development v7.15 ISCA-46300-Loss Arina Puzriakova changed review comment from: https://search.clinicalgenome.org/kb/gene-dosage/region/ISCA-46300

ClinGen review: Deletion of the 15q24 recurrent region (C-D) has been reported in at least 4 patients with a syndromic clinical phenotype characterized by developmental delays (speech and motor), intellectual disability, brain anomalies, craniofacial abnormalities, hypermobile joints, digital findings, and other variable clinical features. Two additional patients have also been reported with atypical deletions encompassed by the 15q24 LCR C-D region, but with breakpoints proximal to LCR D. Both of these patients had a similar clinical presentation to patients with the typical 15q24 LCR C-D deletion. Parental studies have demonstrated that each of the deletions in this region (6 total) represent de novo events. Case-control data are currently uninformative due to the rarity of this deletion. The known haploinsufficient gene SIN3A is thought to represent the critical gene within this region, as SIN3A sequence level have a similar clinical presentation to recurrent deletion.
