Genes affected

PRIMA1 (HGNC:18319): (proline rich membrane anchor 1) The product of this gene functions to organize acetylcholinesterase (AChE) into tetramers, and to anchor AChE at neural cell membranes. [provided by RefSeq, Nov 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BP6: Variant 14-93721498-G-C is Benign according to our data. Variant chr14-93721498-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 2106710.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.935 with no splicing effect.
