Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2024The c.787G>A (p.D263N) alteration is located in exon 9 (coding exon 8) of the BABAM1 gene. This alteration results from a G to A substitution at nucleotide position 787, causing the aspartic acid (D) at amino acid position 263 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
