Genes affected

CISD2 (HGNC:24212): (CDGSH iron sulfur domain 2) The protein encoded by this gene is a zinc finger protein that localizes to the endoplasmic reticulum. The encoded protein binds an iron/sulfur cluster and may be involved in calcium homeostasis. Defects in this gene are a cause of Wolfram syndrome 2. [provided by RefSeq, Mar 2011]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.71).
• BP6: Variant 4-102869199-C-G is Benign according to our data. Variant chr4-102869199-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 2021755.Status of the report is criteria_provided_single_submitter, 1 stars.
