Genes affected

SHROOM3 (HGNC:30422): (shroom family member 3) This gene encodes a PDZ-domain-containing protein that belongs to a family of Shroom-related proteins. This protein may be involved in regulating cell shape in certain tissues. A similar protein in mice is required for proper neurulation. [provided by RefSeq, Jan 2011]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP6: Variant 4-76436045-T-A is Benign according to our data. Variant chr4-76436045-T-A is described in ClinVar as [Benign]. Clinvar id is 3040646.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAd at 5 AR gene
