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.
