Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 21, 2022The c.754C>T (p.H252Y) alteration is located in exon 11 (coding exon 10) of the SYCP1 gene. This alteration results from a C to T substitution at nucleotide position 754, causing the histidine (H) at amino acid position 252 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
