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]

Collection Method: clinical testing

The c.575C>G (p.P192R) alteration is located in exon 6 (coding exon 6) of the NECAP2 gene. This alteration results from a C to G substitution at nucleotide position 575, causing the proline (P) at amino acid position 192 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
