Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2022The c.6G>C (p.W2C) alteration is located in exon 1 (coding exon 1) of the RBFA gene. This alteration results from a G to C substitution at nucleotide position 6, causing the tryptophan (W) at amino acid position 2 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
