TYR M1V - GET-Evidence



(TYR Met1Val)

Short summary

Reported to cause oculocutaneous albinism in a recessive manner. This effect is recorded in ClinVar by OMIM (http://www.ncbi.nlm.nih.gov/clinvar/RCV000004011/), and comes from Fukai et al 1995 (PMID: 7704033) who found this variant carried heterozygously by one of 12 patients studied.
