Table 3. TYR gene mutations in patients with Oculocutaneous albinism 1 (OCA1) in Indian families
This table describes two novel frameshift mutations and a known nonsense mutation in TYR gene in Indian OCA1 patients. The five exons of the TYR gene were sequenced for each individual using PCR followed by bi-directional sequencing, and the findings are shown.
