Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_020200.7(PRTFDC1):c.576C>A(p.Asn192Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000066 in 151,504 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. N192D) has been classified as Likely benign.

The c.576C>A (p.N192K) alteration is located in exon 8 (coding exon 8) of the PRTFDC1 gene. This alteration results from a C to A substitution at nucleotide position 576, causing the asparagine (N) at amino acid position 192 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
