Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2 PP2 BP4_Strong

The NM_001366145.2(TRPM3):​c.4718C>T​(p.Ala1573Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

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]

KLF9-DT (HGNC:):

ACMG classification

Verdict is Likely_benign. 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=0.058534086).
