Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001040274.3(SYCP2L):​c.22G>T​(p.Ala8Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Genomes: not found (cov: 30)
• Consequence: SYCP2L NM_001040274.3 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: -0.936

Genes affected

SYCP2L (HGNC:21537): (synaptonemal complex protein 2 like) Predicted to be involved in meiotic nuclear division. Predicted to act upstream of or within negative regulation of cell death. Located in condensed chromosome, centromeric region and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

The c.22G>T (p.A8S) alteration is located in exon 2 (coding exon 2) of the SYCP2L gene. This alteration results from a G to T substitution at nucleotide position 22, causing the alanine (A) at amino acid position 8 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
