Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.220C>A (p.P74T) alteration is located in exon 1 (coding exon 1) of the MAS1L gene. This alteration results from a C to A substitution at nucleotide position 220, causing the proline (P) at amino acid position 74 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
