Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The ENST00000298229.7(INPPL1):​c.753G>C​(p.Gln251His) variant causes a missense, splice region change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as no classification for the single variant (no stars).

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

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Multiple lines of computational evidence support a deleterious effect 7: BayesDel_addAF, BayesDel_noAF, Cadd, dbscSNV1_ADA, dbscSNV1_RF, max_spliceai, M_CAP [when AlphaMissense, Eigen, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
