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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 26, 2024The c.563T>C (p.L188P) alteration is located in exon 6 (coding exon 6) of the NECAP2 gene. This alteration results from a T to C substitution at nucleotide position 563, causing the leucine (L) at amino acid position 188 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
