ABCC7 p.Gly551Lys

ClinVar: c.1651G>A , p.Gly551Ser D , Pathogenic
c.1652G>A , p.Gly551Asp D , Pathogenic
CF databases: c.1652G>A , p.Gly551Asp D , CF-causing ; CFTR1: This mutation has been found in six Caucasian CF chromosomes out of 155 eamined for a frequency of 4 %. It has not been found on any Black CF chromosomes. This mutation appears to be associated with a particular ten site haplotype shown on the following pages. We have not detected this mutation on any normal Caucasian chromosomes with similar haplotypes or other haplotypes.
c.1651G>A , p.Gly551Ser D , CF-causing ; CFTR1: This mutation can be detected using ASOs: normal 5' GAGTGGAGGTCAACG 3', mutant 5' GAGTGGAAGTCAACG 3' with a final wash at 42 degrees celsius in 40 mM NaHPO4, 1 mM EDTA, 0.5 % SDS for 15 minutes. Two patients were found to be homozygous for this mutation. Their parents are second cousins and each carries the G551S mutation. These patients are remarkable in that they have a mild disease without elevated Na+ levels. One patient had decreased lung function, Pseudomonas infections, chronic pancreatitis, clubbing, and is currently 49 years old. This mutation was not found in 363 non-[delta]F508 CF chromosomes, nor in over 700[delta]F508 chromosomes, nor in a small number of normal chromosomes.
