Homozygotes for a null allele show low serum FGF23 levels, hyperphosphatemia, normal 1,25-dihydroxyvitamin D levels, and male-specific growth retardation, sterility and increased bone density. Males homozygous for another null allele show abnormal acrosome assembly and oligoasthenoteratozoospermia.
