XQTL

XQTL is a family-based allelic/haplotype association test for quantitative traits using X-linked SNP/two-locus markers in a nuclear family design. XQTL adopts the framework of the orthogonal model implemented in the QTDT program with modification of the sex-specific score for X-linked genotypes. XQTL also takes into account the dosage effect due to female X chromosome inactivation.
