Heterogeneity in the mutations responsible for X chromosome-linked Kallmann syndrome
Abstract
Kallmann syndrome represents the association of hypogonadotropic hypogonadism with anosmia. Three modes of transmission, X chromosome-linked, autosomal recessive and autosomal dominant, have been described. The KAL gene, responsible for the X-linked form of the disease, has been isolated and its intron-exon organization recently determined. We have searched for mutations of the KAL gene in 21 unrelated males affected by familial Kallmann syndrome. In these families, segregation of the disease was suggestive of the X-linked mode of transmission. In 2 families, large Xp22.3 deletions, both including the entire KAL gene, have been detected by Southern blot analysis. Here we report the sequence analysis of the entire coding region of the KAL gene in the 19 remaining patients. The approach consisted of sequencing each of the 14 coding exons and splice site junctions. Each exon was amplified by PCR on the genomic DNA, using oligonucleotides from the flanking intronic sequences as specific primers. Nine point mutations were identified at separate locations in four exons and one splice site, providing strong evidence for heterogeneity in mutations responsible for the X-linked Kallmann syndrome. In addition, the high frequency of unilateral renal aplasia in X-linked Kallmann patients (6 out of 11 males with identified alterations of the KAL gene) should be emphasized.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
