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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.217G>A (p.V73M) alteration is located in exon 3 (coding exon 3) of the NECAP2 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the valine (V) at amino acid position 73 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
