Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_020921.4(NIN):c.6156G>T(p.Arg2052Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000415 in 1,613,962 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2052G) has been classified as Likely benign.

Submissions by phenotype
not specified Uncertain:1
The c.6156G>T (p.R2052S) alteration is located in exon 30 (coding exon 28) of the NIN gene. This alteration results from a G to T substitution at nucleotide position 6156, causing the arginine (R) at amino acid position 2052 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with NIN-related conditions. This variant is present in population databases (rs534805269, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 2052 of the NIN protein (p.Arg2052Ser). -
