Genes affected

TRPM4 (HGNC:17993): (transient receptor potential cation channel subfamily M member 4) The protein encoded by this gene is a calcium-activated nonselective ion channel that mediates transport of monovalent cations across membranes, thereby depolarizing the membrane. The activity of the encoded protein increases with increasing intracellular calcium concentration, but this channel does not transport calcium. [provided by RefSeq, Mar 2016]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 19-49166225-G-A is Benign according to our data. Variant chr19-49166225-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 468937.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High AC in GnomAdExome at 6 AD gene.
