Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.794G>T (p.S265I) alteration is located in exon 6 (coding exon 6) of the MLLT1 gene. This alteration results from a G to T substitution at nucleotide position 794, causing the serine (S) at amino acid position 265 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
