Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2022The c.997A>T (p.I333F) alteration is located in exon 7 (coding exon 7) of the PALMD gene. This alteration results from a A to T substitution at nucleotide position 997, causing the isoleucine (I) at amino acid position 333 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
