NM_012469.4:c.2185C>T
Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The NM_012469.4(PRPF6):c.2185C>T(p.Arg729Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000089 in 1,461,402 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R729Q) has been classified as Uncertain significance.

This variant disrupts the p.Arg729 amino acid residue in PRPF6. Other variant(s) that disrupt this residue have been observed in individuals with PRPF6-related conditions (Invitae), which suggests that this may be a clinically significant amino acid residue. This sequence change replaces arginine with tryptophan at codon 729 of the PRPF6 protein (p.Arg729Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with retinitis pigmentosa (PMID: 21549338). ClinVar contains an entry for this variant (Variation ID: 31089). Experimental studies have shown that this variant affects PRPF6 protein function (PMID: 21549338). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
