Genes affected

INPPL1 (HGNC:6080): (inositol polyphosphate phosphatase like 1) The protein encoded by this gene is an SH2-containing 5'-inositol phosphatase that is involved in the regulation of insulin function. The encoded protein also plays a role in the regulation of epidermal growth factor receptor turnover and actin remodelling. Additionally, this gene supports metastatic growth in breast cancer and is a valuable biomarker for breast cancer. [provided by RefSeq, Jan 2009]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 1 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BP6: Variant 11-72230337-A-G is Benign according to our data. Variant chr11-72230337-A-G is described in ClinVar as Benign. ClinVar VariationId is 1289494.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.568 is higher than 0.05.
