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 GeneticsDec 19, 2023The c.673C>A (p.L225I) alteration is located in exon 7 (coding exon 7) of the NECAP2 gene. This alteration results from a C to A substitution at nucleotide position 673, causing the leucine (L) at amino acid position 225 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
