| Identified Mutation |
ARG500TER; In a Pakistani family, Riazuddin et al. (Am J Hum Genet 79:1040-1051, 2006) found that autosomal recessive neurosensory deafness (DFNB49; 610153) was related to a 1498C-T transition in exon 5 of the MARVELD2 gene that resulted in an arg500-to-stop substitution (R500X).

| Remarks |
Clinically normal father of four affected children; affected son is GM20189; donor subject is heterozygous for a C>T transition at nucleotide 1498 in exon 5 of the MARVELD2 (TRIC) gene (c.1498C>T) resulting in an arg500-to-stop substitution [Arg500Ter (R500X)] |
