Variant:

1946-4C→T (intronic), Exon 16

7630C→T (Gln2544X), Exon 45

Compound Heterozygous

Note: Article assumes that 1946-4C→T is a frameshift mutation. No potential splice site mutation was confirmed at the mRNA level; “Splice Site Prediction program” found all mutations likely to disrupt normal splicing. No possible splice site mutation could be identified on 100 chromosomes from a group of 50 normal subjects with same genetic background as patients, excluding the possibility that these mutations represent common polymorphisms.
