Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.428C>A (p.T143K) alteration is located in exon 4 (coding exon 4) of the RBFA gene. This alteration results from a C to A substitution at nucleotide position 428, causing the threonine (T) at amino acid position 143 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
