This sequence change replaces isoleucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1002 of the TRPM1 protein (p.Ile1002Phe). This variant is present in population databases (rs369484186, gnomAD 0.004%). This missense change has been observed in individual(s) with congenital stationary night blindness (PMID: 19878917, 28041643, 29074561, 35633130). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as p.Ile1041Phe. ClinVar contains an entry for this variant (Variation ID: 290045). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TRPM1 protein function. For these reasons, this variant has been classified as Pathogenic. -
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 19878917, 28041643, 32581362, 35633130, 29074561, 36284670, 35456422) -
