Genetic Variant SLF2:p.Pro171Ser (chr10-100916896-C-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_018121.4(SLF2):c.511C>T(p.Pro171Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000123 in 1,461,862 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. P171L) has been classified as Uncertain significance.

Genes affected

SLF2 (HGNC:17814): (SMC5-SMC6 complex localization factor 2) Enables ubiquitin protein ligase binding activity. Involved in several processes, including positive regulation of cellular component organization; positive regulation of double-strand break repair; and protein localization to site of double-strand break. Located in chromatin; nucleoplasm; and site of double-strand break. [provided by Alliance of Genome Resources, Apr 2022]

The c.511C>T (p.P171S) alteration is located in exon 3 (coding exon 3) of the SLF2 gene. This alteration results from a C to T substitution at nucleotide position 511, causing the proline (P) at amino acid position 171 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
