| pubmed-article:1997381 | pubmed:abstractText | A case of homozygous factor X deficiency arising from the inheritance of two non-identical gene deletions from heterozygous parents is described. One, a partial gene deletion, was localized to exons VII and VIII by a combination of Southern blotting and polymerase chain reaction (PCR) amplification of exon sequences. The other deletion, of maternal origin, probably involves the entire factor X gene. Restriction fragments associated with the exon VII + VIII deletion were present in three siblings including the homozygous proband. These fragments were however absent from the somatic cells of the father, a finding consistent with germline mosaicism. | lld:pubmed |
