Genes affected

SCRN1 (HGNC:22192): (secernin 1) This gene likely encodes a member of the secernin family of proteins. A similar protein in rat functions in regulation of exocytosis in mast cells. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 7-29923318-C-T is Benign according to our data. Variant chr7-29923318-C-T is described in ClinVar as [Benign]. Clinvar id is 1257931.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.402 is higher than 0.05.
