Marie Unna hereditary hypotrichosis (MUHH) is an autosomal dominant form of genetic hair loss. U2HR gene dysfunction has been identified as the pathogenic change of this disease. Herein we present a four-generation Chinese family of 15 patients carrying MUHH, and detected a recurrent missense mutation in U2HR gene, c.74C>T (p.P25L), previously reported in a Jewish Ashkenazi MUHH family. The literature review concluded that there were 16 mutations of the U2HR gene in patients with MUHH of different origins, and indicated two mutation hot spots (amino acids 1–7 and 24–28) but no clear genotype–phenotype correlations.
