Genes affected

TRPM3 (HGNC:17992): (transient receptor potential cation channel subfamily M member 3) The product of this gene belongs to the family of transient receptor potential (TRP) channels. TRP channels are cation-selective channels important for cellular calcium signaling and homeostasis. The protein encoded by this gene mediates calcium entry, and this entry is potentiated by calcium store depletion. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TRPM3. . Gene score misZ 3.1768 (greater than the threshold 3.09). Trascript score misZ 3.8237 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, schizophrenia, autosomal dominant non-syndromic intellectual disability, cataract-glaucoma syndrome, neurodevelopmental disorder with hypotonia, dysmorphic facies, and skeletal anomalies, with or without seizures, cataract 50 with or without glaucoma.

BP4

Computational evidence support a benign effect (MetaRNN=0.07015699).

The c.4934C>A (p.A1645E) alteration is located in exon 25 (coding exon 25) of the TRPM3 gene. This alteration results from a C to A substitution at nucleotide position 4934, causing the alanine (A) at amino acid position 1645 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
