Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.452C>T (p.P151L) alteration is located in exon 7 (coding exon 4) of the FAM149A gene. This alteration results from a C to T substitution at nucleotide position 452, causing the proline (P) at amino acid position 151 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
