Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.778C>T (p.H260Y) alteration is located in exon 8 (coding exon 8) of the SERGEF gene. This alteration results from a C to T substitution at nucleotide position 778, causing the histidine (H) at amino acid position 260 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
