dbSNP rs7501939: HNF1B:c.345-1526G>C (chr17-37741165-C-G) – ACMG Classification: Likely_benign (-2 pts)

Germline classification Cancer classification (beta)

Variant summary

Our verdict is . The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_000458.4(HNF1B):c.345-1526G>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

HNF1B (HGNC:11630): (HNF1 homeobox B) This gene encodes a member of the homeodomain-containing superfamily of transcription factors. The protein binds to DNA as either a homodimer, or a heterodimer with the related protein hepatocyte nuclear factor 1-alpha. The gene has been shown to function in nephron development, and regulates development of the embryonic pancreas. Mutations in this gene result in renal cysts and diabetes syndrome and noninsulin-dependent diabetes mellitus, and expression of this gene is altered in some types of cancer. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PM2

Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD/XL) (threshold 0.0001) — PM2 moderate.

BP4

Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
