Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2021The c.658A>G (p.T220A) alteration is located in exon 9 (coding exon 9) of the SYCP2L gene. This alteration results from a A to G substitution at nucleotide position 658, causing the threonine (T) at amino acid position 220 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
