Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1 PM2 PP5

The NM_001134673.4(NFIA):c.1094del(p.Pro365HisfsTer32) variant causes a frameshift change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. P365P) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected

NFIA (HGNC:7784): (nuclear factor I A) This gene encodes a member of the NF1 (nuclear factor 1) family of transcription factors. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-61404120-AC-A is Pathogenic according to our data. Variant chr1-61404120-AC-A is described in ClinVar as [Pathogenic]. Clinvar id is 417968.Status of the report is no_assertion_criteria_provided, 0 stars.
