chr17-1509784-T-C

Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2 PP3_Moderate PP5

The NM_016532.4(INPP5K):c.277A>G(p.Met93Val) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M93I) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)

Genes affected

INPP5K (HGNC:33882): (inositol polyphosphate-5-phosphatase K) This gene encodes a protein with 5-phosphatase activity toward polyphosphate inositol. The protein localizes to the cytosol in regions lacking actin stress fibers. It is thought that this protein may negatively regulate the actin cytoskeleton. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.935
• PP5: Variant 17-1509784-T-C is Pathogenic according to our data. Variant chr17-1509784-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 417779.Status of the report is no_assertion_criteria_provided, 0 stars.
