Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.320T>C (p.M107T) alteration is located in exon 3 (coding exon 3) of the BCAS4 gene. This alteration results from a T to C substitution at nucleotide position 320, causing the methionine (M) at amino acid position 107 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
