Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_015509.4(NECAP1):​c.26C>A​(p.Ser9Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,552 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S9C) has been classified as Uncertain significance.

Genes affected

NECAP1 (HGNC:24539): (NECAP endocytosis associated 1) This gene encodes a protein containing two characteristic WXXF motifs. The encoded protein localizes to clathrin-coated vesicles, where it binds components of the adapter protein complexes and aids in endocytosis. Loss of function of this gene results in early infantile epileptic encephalopathy-21. There is a pseudogene for this gene on chromosome 7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ENSG00000284697 (HGNC:):

ACMG classification
