Intellectual disability v9.174 ISCA-37498-Loss Arina Puzriakova changed review comment from: https://search.clinicalgenome.org/kb/gene-dosage/region/ISCA-37498

ClinGen review: Reported in at least 2 individuals with developmental delay/intellectual disability, dysmorphic features, dental anomalies, long slender fingers with 5th finger clinodactyly, and additional clinical features. Another patient (PMID: 28018436) was reported to have an overlapping 11q13 deletion that involves most of the recurrent region with a similar clinical phenotype. All reported deletions of the recurrent 11q13.2q13.4 region with informative parental testing have been shown to be de novo. Case-control data are currently uninformative due to the rarity of this deletion. Additionally, this deletion encompasses two curated dosage sensitive genes, KMT5B and SHANK2.

Intellectual disability v3.1519 ANK2 Ivone Leong Tag Q3_21_rating was removed from gene: ANK2.
Intellectual disability v3.1519 ANK2 Sarah Leigh commented on gene: ANK2
Intellectual disability v3.1519 ANK2 Ivone Leong Source Expert Review Green was added to ANK2.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability v3.1296 ANK2 Arina Puzriakova Classified gene: ANK2 as Amber List (moderate evidence)
Intellectual disability v3.1296 ANK2 Arina Puzriakova Added comment: Comment on list classification: New gene added by Zornitza Stark. There is sufficient evidence to promote this gene to Green at the next GMS panel review - sufficient unrelated cases with relevant phenotype and de novo PTVs in this gene. Definitive gene-disease association is supported by the ClinGen ID and Autism Expert Panel.
