Comment on list classification: New gene added and rated Green by Zornitza Stark. Sufficient evidence and appropriate phenotype (all affected individuals present progressive severe microcephaly, generalised tonic clonic seizures with onset at 1 - 7 months, diabetes diagnosed at 4 weeks - 15 months, and 5/6 also had severe DD) for inclusion on this panel: 6 patients from 5 families with different YIPF5 variants identified in PMID: 33164986. Functional analysis demonstrated that YIPF5 deficiency enhances ER stress and sensitises beta-cells to ER stress-induced apoptosis.

YIPF5 is also associated with a relevant phenotype in OMIM (MIM# 619278) but is not yet listed in G2P.

There is enough evidence to rate this gene as Green at the next GMS panel update.

Green List (high evidence)

Six individuals from 5 unrelated consanguineous families reported with bi-allelic variants in this gene and neonatal/early-onset diabetes, severe microcephaly, and epilepsy. Functional data supports gene-disease association.
