Variant chr1-16443672-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_018090.5(NECAP2):c.133C>T(p.Arg45Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000157 in 1,460,484 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R45Q) has been classified as Uncertain significance.

Genes affected

NECAP2 (HGNC:25528): (NECAP endocytosis associated 2) This gene likely encodes a member of the adaptin-ear-binding coat-associated protein family. Studies of a similar protein in rat suggest a role in clathrin-mediated endocytosis. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2009]

May 21, 2024

The c.133C>T (p.R45W) alteration is located in exon 2 (coding exon 2) of the NECAP2 gene. This alteration results from a C to T substitution at nucleotide position 133, causing the arginine (R) at amino acid position 45 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
