Genes affected

AMPH (HGNC:471): (amphiphysin) This gene encodes a protein associated with the cytoplasmic surface of synaptic vesicles. A subset of patients with stiff-man syndrome who were also affected by breast cancer are positive for autoantibodies against this protein. Alternate splicing of this gene results in two transcript variants encoding different isoforms. Additional splice variants have been described, but their full length sequences have not been determined. A pseudogene of this gene is found on chromosome 11.[provided by RefSeq, Nov 2010]

Ambry Genetics

May 11, 2022

The c.1625C>T (p.S542L) alteration is located in exon 19 (coding exon 19) of the AMPH gene. This alteration results from a C to T substitution at nucleotide position 1625, causing the serine (S) at amino acid position 542 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
