Genes affected

NFIX (HGNC:7788): (nuclear factor I X) The protein encoded by this gene is a transcription factor that binds the palindromic sequence 5'-TTGGCNNNNNGCCAA-3 in viral and cellular promoters. The encoded protein can also stimulate adenovirus replication in vitro. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2012]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NFIX. . Gene score misZ 4.0788 (greater than the threshold 3.09). Trascript score misZ 5.3516 (greater than threshold 3.09). GenCC has associacion of gene with Marshall-Smith syndrome, Malan overgrowth syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.927
• PP5: Variant 19-13025330-A-G is Pathogenic according to our data. Variant chr19-13025330-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 559884.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr19-13025330-A-G is described in Lovd as [Pathogenic].
