The KAL1 pVal610Ile mutation is a recessive mutation causing Kallmann syndrome

A missense mutation of KAL1, c.1828G>A, led to pVal610Ile substitution in two brothers with Kallmann syndrome; their mother is heterozygous for this missense mutation encoded by the single-nucleotide polymorphism rs2229013.

Abstract

Objective:

To present clinical, genetic, biochemical, and molecular findings in two Chinese siblings with X-linked recessive KS.

Design:

Case report.

Setting:

University medical center.

Patient(s):

Two Chinese siblings.

Intervention(s):

Clinical evaluation, hormone assays, gene mutation research.

Main Outcome Measure(s):

Endocrinologic evaluation and genetic analysis.

Result(s):

A missense mutation of KAL1, c.1828G﹥A, which lead to pVal610Ile substitution in the two brothers with KS while their mother was heterozygous for this missense mutation encoded by SNP rs2229013.

Conclusion(s):

Mutation analysis revealed that a missense mutation of KAL1 in two brothers with KS, while their mother was heterozygous for this missense mutation encoded by the single-nucleotide polymorphism rs2229013. Variant alleles of KAL1 related to X-linked recessive KS expand the spectrum of KAL1 mutations causing KS.
