We report on a 5p- azoospermic male not showing the clinical features diagnostic for the cri-du-chat syndrome but for a breathy, raspy voice. The 5p deletion breakpoint, determined by fluorescent in situ hybridization (FISH) analysis with BAC clones, maps 8.5 Mb far from the short arm telomere in 5p15.31. Genotype/phenotype correlations in this subject, including his neuropsychological assessment, led us to define that the gene for the cat-like cry and one gene responsible for mild mental retardation with speech delay map both in the distal 8.5 Mb of chromosome 5 short arm.
