Variant summary

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

The NM_001145313.3(FSD1L):c.487C>T(p.Arg163Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000983 in 1,525,672 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. R163H) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.487C>T (p.R163C) alteration is located in exon 7 (coding exon 7) of the FSD1L gene. This alteration results from a C to T substitution at nucleotide position 487, causing the arginine (R) at amino acid position 163 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
