Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2022The c.303G>C (p.K101N) alteration is located in exon 3 (coding exon 3) of the BCAS4 gene. This alteration results from a G to C substitution at nucleotide position 303, causing the lysine (K) at amino acid position 101 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
