Genes affected

RGN (HGNC:9989): (regucalcin) The protein encoded by this gene is a highly conserved, calcium-binding protein, that is preferentially expressed in the liver and kidney. It may have an important role in calcium homeostasis. Studies in rat indicate that this protein may also play a role in aging, as it shows age-associated down-regulation. This gene is part of a gene cluster on chromosome Xp11.3-Xp11.23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.37).
• BP6: Variant X-47084584-C-T is Benign according to our data. Variant chrX-47084584-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 2660394.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.822 with no splicing effect.
• BS2: High Hemizygotes in GnomAdExome4 at 6 gene
