Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.152C>T (p.A51V) alteration is located in exon 3 (coding exon 2) of the SYCP1 gene. This alteration results from a C to T substitution at nucleotide position 152, causing the alanine (A) at amino acid position 51 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
