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]

Mar 25, 2024

The c.557G>C (p.S186T) alteration is located in exon 6 (coding exon 6) of the NECAP2 gene. This alteration results from a G to C substitution at nucleotide position 557, causing the serine (S) at amino acid position 186 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
