Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.880C>T (p.H294Y) alteration is located in exon 6 (coding exon 6) of the GSG1L gene. This alteration results from a C to T substitution at nucleotide position 880, causing the histidine (H) at amino acid position 294 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
