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 -14 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_017636.4.
• BP6: Variant 19-49196501-TGCTGCGGGGGCC-T is Benign according to our data. Variant chr19-49196501-TGCTGCGGGGGCC-T is described in ClinVar as [Likely_benign]. Clinvar id is 415729.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-49196501-TGCTGCGGGGGCC-T is described in Lovd as [Benign]. Variant chr19-49196501-TGCTGCGGGGGCC-T is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.124 is higher than 0.05.
