Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PVS1 PM2 PP5_Moderate

The NM_001008537.3(NEXMIF):​c.3470C>A​(p.Ser1157*) variant causes a stop gained change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. S1157S) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected

NEXMIF (HGNC:29433): (neurite extension and migration factor) An inversion on the X chromosome which disrupts this gene and a G-protein coupled purinergic receptor gene located in the pseudoautosomal region of the X chromosome has been linked to X linked cognitive disability.[provided by RefSeq, Mar 2009]

NEXMIF Gene-Disease associations (from GenCC):

• X-linked complex neurodevelopmental disorder

  Inheritance: XL Classification: DEFINITIVE Submitted by: ClinGen
• X-linked intellectual disability, Cantagrel type

  Inheritance: XL Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae)
• myoclonic-astatic epilepsy

  Inheritance: Unknown Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Pathogenic. The variant received 12 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 X-74741087-G-T is Pathogenic according to our data. Variant chrX-74741087-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 397512.Status of the report is criteria_provided_single_submitter, 1 stars.
