| Gene |
FANCC |
| Chromosomal Location |
9q22.3 |
| Allelic Variant 1 |
227645.0003; FANCONI ANEMIA, COMPLEMENTATION GROUP C |
| Identified Mutation |
IVS,A>T,+4; Using reverse transcription PCR and chemical mismatch cleavage (CMC), Whitney et al. (Nat Genet 4:202-205, 1993) demonstrated homozygosity for an identical splice mutation in 2 Ashkenazi Jewish patients with Fanconi anemia. Three additional patients bearing this allele were found through screening 21 other families. A single base change in the fourth intronic base changed the sequence from a consensus A to T, resulting in deletion of the 111-bp exon 4. They referred to the allele as IVS4+4, A-to-T. |

| Remarks |
Clinically affected; complementation group C; pancytopenia; classical symptoms; increased incidence of chromatid breaks and gaps following x-irradiation during G2; low-normal NAD+ levels in cells: 973 +/- 454 pmol/million cells (mean for normal cells = 1,140 +/- 304 pmol/million cells); donor subject is homozygous for a splice site mutation [IVS4+4A>T] in the FANCC gene in which a single base change in the fourth intronic base changes the sequence from a consensus A to T, resulting in deletion of the 111-bp exon 4; see GM13136 SV40 Transformed Fibroblast.
