Intellectual disability v8.103 ISCA-37447-Loss Arina Puzriakova Classified Region: ISCA-37447-Loss as Green List (high evidence)
Intellectual disability v8.103 ISCA-37447-Loss Arina Puzriakova Region: isca-37447-loss has been classified as Green List (High Evidence).
Intellectual disability v8.102 ISCA-37447-Loss Arina Puzriakova Added comment: Comment on mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown has been agreed for the R29 Intellectual disability panel. This would capture both imprinting patterns where there is clinical overlap between Kagami-Ogata and Temple syndrome which are both relevant to this panel.

These disorders are suitable for R27 Paediatric disorders and R69 Hypotonic infant super panels (included via R29)
Intellectual disability v8.102 ISCA-37447-Loss Arina Puzriakova Mode of inheritance for Region: ISCA-37447-Loss was changed from MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Intellectual disability v8.101 ISCA-37447-Loss Arina Puzriakova Region: ISCA-37447-Loss was added
Region: ISCA-37447-Loss was added to Intellectual disability. Sources: ClinGen
Mode of inheritance for Region: ISCA-37447-Loss was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for Region: ISCA-37447-Loss were set to 20585555; 24801763; 27406249; 33579810; 18176563; 28640239
Phenotypes for Region: ISCA-37447-Loss were set to Kagami-Ogata syndrome, OMIM:608149; Temple syndrome, OMIM:616222
Review for Region: ISCA-37447-Loss was set to GREEN
Added comment: Multiple unrelated cases curated in ClinGen - sufficient evidence to add this region (https://search.clinicalgenome.org/kb/gene-dosage/region/ISCA-37447)

DLK1-MEG3 Intergenic Region includes the paternally expressed DLK1 gene, the 2 differentially methylated regions (DMRs) DLK1/MEG3:IG-DMR and MEG3:TSS-DMR, and the 5' end of the maternally expressed gene MEG3 (4 exons).

The phenotype depends on the parental origin: Kagami Ogata syndrome/KOS (maternally derived imprinting) or Temple syndrome/TS (paternally derived imprinting)

Kagami-Ogata syndrome is characterized by typical facial features, skeletal abnormalities (including ""coat-hanger ribs"", and bell-shaped thorax), abdominal wall defects, and developmental delay.

Temple syndrome is a less specific phenotype including intrauterine and postnatal growth restriction, hypotonia, feeding difficulties in infancy, truncal obesity, and small feet and hands.
