Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.563A>G (p.Y188C) alteration is located in exon 1 (coding exon 1) of the MAS1L gene. This alteration results from a A to G substitution at nucleotide position 563, causing the tyrosine (Y) at amino acid position 188 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
