Genes affected

NFIA-AS2 (HGNC:40401): (NFIA antisense RNA 2)

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]

NFIA Gene-Disease associations (from GenCC):

• brain malformations with or without urinary tract defects

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), ClinGen
• chromosome 1p32-p31 deletion syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Illumina, Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.108 is higher than 0.05.
