24936977 SMPX is localized predominantly in repetitive double stripes flanking the Z-disc, and not present in nuclei.
24687041 Audiological, medical, and family histories were collected and family members interviewed to compare hearing thresholds and case histories between cases with mutations in SMPX versus POU3F4.
22911656 Data indicate founder mutation in exon 3 (c.99delC) of SMPX that cosegregates in two Newfoundland families.
21893181 Demonstrate phenotypic heterogeneity in large family with an X-linked pattern of inherited sensorineural hearing impairment with SMPX mutations.
21549342 This study identifies SMPX as a gene in which variation is associated with X-linked deafness and illustrates that NGS is instrumental in the efficient identification of disease-causing variants in unexpected genes.
21549336 Our study identified mutations in SMPX in patients with X-chromosomal hearing impairment and suggested that the stress response of mechanically challenged inner-ear cells might critically depend on SMPX function.
